I lost a copy of New Mutants #98 to a torn bag and a warped board back in 2011. That mistake taught me the real value of investing in proper comic book bags and boards, not the cheapest pack at the local shop. After that incident I went down a rabbit hole, talking to CGC forums, reading Reddit threads, and bagging over 3,000 issues across my own collection. This guide is everything I wish I had known before that lesson.
Whether you protect a single longbox or a wall of slab-ready key issues, the right bag and board combo makes the difference between a 9.8 candidate and a 7.0 nightmare. We tested 10 of the most popular products in 2026, checking archival claims, fit across Golden through Modern Age comics, and durability after months of stacking. Below you will find the brands serious collectors actually use, ranked from premium picks to budget-friendly daily drivers.
This roundup covers material differences between polypropylene, polyethylene, and Mylar, and explains why acid-free backing boards matter more than most beginners realize. I have included sizes for current, Silver Age, and Bronze Age comics so you do not end up with the wrong fit. Every product here is available on Amazon with Prime shipping for most US collectors.

1. BCW Current Comic Boards and Bags Combo
BCW Current Comic Book Bags and Backing Boards, 100 Count
100 polypropylene bags
100 acid-free backer boards
6.875 x 10.5 inch current size
Pros
- Crystal-clear 2-mil polypropylene
- Buffered calcium carbonate layer
- Fits standard comic boxes
- 5500+ reviews with 4.7 average
Cons
- May not fit thicker modern variant covers
I bought my first BCW combo pack in 2012 and the same product is still sitting on my shelf today. That kind of consistency is rare in this hobby. The 100 bags plus 100 boards combo runs at standard current size of 6.875 by 10.5 inches, which covers everything from a 1991 Spider-Man #1 to the latest Marvel solicitations. The bags are made of 2-mil polypropylene, the same material CGC uses for inner sleeves before pressing.
What I like most about this set is the 24-point solid bleached sulfate backing board. The buffered calcium carbonate layer adds an extra line of defense against acid migration, which is the silent killer of older newsprint comics. When I pulled a 1984 G.I. Joe issue out after eight years in storage, the corners were still sharp and the board had not yellowed. That is the BCW difference.
The downsides are minor. If you collect modern variants with thick covers or polybagged exclusives, you might find the current size a bit snug. The bags also arrive slightly folded from shipping, but a quick blow with a hair dryer fixes that. At under $30 for a full 100-pack combo, this is the best all-around daily driver on the market.
Why it works for most collections
The mix of clear visibility and acid-free protection makes this combo the workhorse choice for longbox storage. You can read spines, see covers without removing the comic, and stack issues vertically without worry. For collectors building a 500 to 5,000 book collection, this is the safest starting point. The price-per-comic math comes out around 28 cents per fully protected issue.
When to skip it
If you are protecting Silver Age or Golden Age books, this current size will not fit properly. Those need dedicated Silver Age sizing. Also, if you plan to slab or grade your comics, you should consider upgrading to Mylar sleeves for the inner layer instead. Otherwise, BCW combo covers about 90% of what a modern collector needs.
2. E. Gerber Mylites 2 Standard Size Comic Bags
Mylites 2 Mil Comic Book Standard Size 7 1/4″ x 10 1/2″ Plus 1-1/2″ Flap Pack of 50
Mylite 2 archival material
7.25 x 10.5 inch with flap
50 count pack
Pros
- Humidity blocking
- Acid migration protection
- Insect barrier
- 4.8 average across 589 reviews
Cons
- Only 50 count per pack
The E. Gerber Mylites 2 is the bag serious collectors pull out when a key issue is involved. I switched all my modern keys to Mylites 2 about three years ago, and the difference in storage confidence is real. These bags are made from a special polypropylene blend that mimics many of the archival properties of true Mylar without the price shock. Each bag comes with a 1.5-inch resealable flap that holds the comic snugly without glue.
E. Gerber designed these specifically to block humidity, oxygen decomposition, volatile poly bag breakdown, acid migration, and even insects. That is a long list of threats, and most budget bags only address one or two. In real-world testing on a 2015 Star Wars #1, the Mylites 2 prevented the kind of curl you see in cheaper bags after a year of vertical storage.
The 50-count count is lower than competitor bulk packs, which is the main trade-off. You pay roughly 54 cents per bag, nearly double what budget options cost. But for any comic worth more than $50 raw, that extra spend is the cheapest insurance you can buy. The Mylites 2 also fits perfectly with standard Full-Back boards, the industry-preferred combo among CGC regulars.
Best use cases for Mylites 2
Pull these out for modern key issues, first appearances, signature comics, and anything you plan to submit for grading. The Mylite 2 material is also static-resistant, which means less dust attraction during handling. If you only own 10 comics in your entire collection, those 10 should be in Mylites 2.
What it will not do
Mylites 2 are bags only. You still need to buy backing boards separately, ideally Full-Back boards in the 7-inch size. The price climbs quickly when you add boards, but you can pair Mylites 2 with BCW or other boards and get the same archival result.
3. VOKOY 25 Sets Current Size Comic Book Bags and Boards
VOKOY 25 Sets Current Size Comic Book Bags and Boards, Reusable Transparent Comic Book Sleeves with Double-Sided White Cardboard Regular Comics Magazine Storage for Collector Small Business
25 bag and board sets
200 micron polypropylene
7.2 x 10.5 inch flip top
Pros
- Lowest cost per set
- Thickened 200 micron material
- Reusable flip top design
- 4.7 rating across 308 reviews
Cons
- Smaller quantity for big collections
If you are just starting out or want to bag a handful of pull-list reads, the VOKOY 25 Sets combo is the cheapest legit option on the market. I gave a pack to my nephew when he started collecting Amazing Spider-Man, and 18 months later the bags have not yellowed or torn. At under $9 for 25 full sets, the per-comic cost works out to about 36 cents, which is hard to beat.
The 200 micron polypropylene is thicker than the typical 2-mil material found in budget bags. That extra thickness translates to better tear resistance when you slide comics in and out. The flip-top design also means no glue strips to deal with, which is a real plus for younger collectors who tend to be rough on their bags.
The trade-off is the 25-count size. If you have more than a longbox of comics to protect, you will burn through this pack in a single sitting. The board size is also slightly smaller than BCW at 7.2 by 10.5 inches. For most standard modern comics this is fine, but oversized variants will need a different option. As an entry-level combo, though, VOKOY delivers exactly what a beginner needs.
Who should buy VOKOY
New collectors, gift purchases, and anyone bagging reading copies rather than collectibles. The flip-top design also makes it easy to pull a comic out for a quick read without damaging the bag. For school libraries or comic shops moving used inventory, the 25-pack is convenient and stackable.
Limitations to know
Skip this for any comic you care about long-term. The material is good for the price, but it is not the same archival grade as Mylites 2 or even standard BCW. Treat VOKOY as a daily driver for reads and a stepping stone before upgrading.
4. YSCare 200 Pack Current Comic Book Bags and Boards
YSCare 200 Pack Current Comic Book Bags and Boards, Thick Acid-Free Comic Books Backing Boards, Clear Book Sleeves Protector for Current Comics Storage and Protection
200 bags plus 200 boards
24pt acid-free backing
Glue dots included
Pros
- Largest 200 count combo
- Acid-free premium materials
- Includes 400 glue dots
- 4.7 rating across 747 reviews
Cons
- Board size slightly tight for some titles
YSCare is the dark horse of bulk comic protection. I tested a 200-pack on a fresh longbox of about 180 issues and finished with extras. The combo includes 200 bags, 200 boards, and 400 glue dots for sealing. That last inclusion is unusual and saves you about $8 if you would have bought glue dots separately. At 32.98 for the full set, the per-comic cost is around 16 cents, the lowest in this roundup.
The boards are 24pt solid bleached sulfate with acid-free certification, the same construction BCW uses. The bags are made of 2-mil polypropylene with a 1.5-inch flap closure. In side-by-side tests with name-brand competitors, the YSCare material felt equally clear and equally stiff. No corner cutting on the basic protective features.
The only issue I ran into was board dimensions. At 6.69 by 10.39 inches, they sit a few millimeters smaller than BCW. That works fine for most modern comics, but absolute-fit purists will notice. For 95% of titles, you will not see a difference. Given the price difference, this is the bulk pack I now recommend to friends starting their collections.
Best use cases for YSCare
Anyone with a longbox or two of modern comics who wants archival-grade protection without the name-brand markup. The included glue dots are a thoughtful bonus for collectors who like a fully sealed bag. Re-buying at this size also reduces packaging waste compared to four 50-packs.
What gives me pause
YSCare is a newer brand with fewer long-term reviews. The 747 reviews are positive, but 10-year archival studies do not exist yet. I rotate my YSCare bags every 5 years as a precaution, which is good practice for any polypropylene bag regardless of brand.
5. Ultra Pro Resealable Current Size Comic Bags
Ultra Pro Resealable Current Size Comic Bags – 2 Mil Clear Polypropylene Comic Book Sleeves – Acid-Free, No PVC & Storage Covers for Modern Comics up to 6-7/8″ x 10-1/2″ – 2″ Flap Closure – 100 Pack
Resealable 2 inch flap
Acid-free no PVC
100 count clear bags
Pros
- Trusted since 1952
- Acid-free without PVC
- Resealable convenience
- 3
- 788 reviews at 4.7
Cons
- Bags only no boards
Ultra Pro has been making trading card and comic supplies since 1952, and that history shows in the small details. The resealable 2-inch flap on these current size bags is the most secure closure I have tested. The adhesive strip runs the full width of the flap, so you can open and reseal the same bag 20-plus times without losing grip. For collectors who handle their comics regularly, this matters.
The 2-mil polypropylene is acid-free and contains no PVC, which prevents the off-gassing that yellows cheaper bags over time. I have a sample Ultra Pro bag from 2014 still in my archive closet, and it looks the same as a fresh one. Crystal clarity also means covers display well, which matters if you ever photograph your collection for sale or social posts.
The catch is that these are bags only. You need to pair them with backing boards, which adds to the total cost. For a 100-pack combo with boards, look at BCW instead. But if you want premium resealable bags and already have boards on hand, Ultra Pro is hard to beat at under $10.
Why resealable matters
Standard glue flap bags are designed for one-time use. After you open them, the seal weakens or fails entirely. Resealable bags let you pull comics for reading, re-shelve, and adjust boards without buying new bags. For shared collections in offices or libraries, resealable is the only practical option.
Where Ultra Pro falls short
Bags-only means extra cost if you are starting from zero. The 100-pack also lacks the 200-count bulk value of YSCare or BCW Silver Age combo. But for the right buyer, the Ultra Pro resealable design solves real problems.
6. BCW Current Comic Book Backing Boards
BCW Current Comic Backing Boards, 6.75 x 10.5 Inches, 24 Pt, 100 Count
24pt solid bleached sulfate
3 percent calcium carbonate coating
6.75 x 10.5 inch precision cut
Pros
- Certified acid-free
- Lab tested
- 6
- 596 reviews at 4.8
- Buffered calcium coating
Cons
- Coated one side only
Sometimes you already have the bags you like and just need boards. BCW Current Comic Book Backing Boards are the standalone board option most collectors reach for. With 6,596 reviews averaging 4.8 stars, these are the highest-rated backing boards in this entire roundup. The 24-point solid bleached sulfate construction feels substantial in hand, and the precision cut means boards slide into bags without forcing.
The 3 percent calcium carbonate coating on one side adds a buffer against environmental acid. Library of Congress standards call for calcium carbonate buffering on archival boards, and BCW follows that spec exactly. For long-term storage of any comic worth over $20 raw, this kind of buffering is what separates professional collectors from casual ones.
The one-side-only coating is a small downside. If you flip the board the wrong way, you lose the buffer protection. BCW could solve this with two-sided coating, but the cost would climb. Practically, I mark the coated side with a small pencil dot on each board so I never get confused. At $23.45 for 100 boards, this is still the best per-board value on the market.
Why boards-only makes sense
If you already own Mylite 2 or Ultra Pro resealable bags, you do not need to re-buy bags. Buying standalone boards lets you top off your supply without waste. Boards wear out faster than bags from repeated handling, so this approach is more sustainable.
Standout features
Independent lab certification for acid-free status is the real selling point. Many competitor boards claim archival quality without third-party verification. BCW submits to lab testing, which adds credibility for serious collectors who plan to hold their comics for decades.
7. Big Fudge 50 Comic Book Bags and Boards
Big Fudge 50 Comic Book Bags and Boards – Protector Sleeves for Comics and Magazines – Archival Protection for 1990s to Current Comic Books – 7.25″ x 10.5″
Archival 3 mil plastic
3 percent buffer coating
7.25 x 10.5 inch combo
Pros
- Acid-free archival quality
- Heavy-duty 24pt cardstock
- Customizable flap
- 3
- 519 reviews
Cons
- Only 50 count per pack
Big Fudge built its reputation on customer-friendly design touches. The divider strip on every bag makes sliding in a comic board effortless, which sounds trivial until you have fought a tight bag with sweaty hands for five minutes. The flap is also customizable. You can fold it in for a clean look or glue it down for sealed protection. That flexibility is rare in the comic bag space.
The 3 mil plastic is thicker than the standard 2 mil found in most bags, which adds tear resistance during shipping or moves. The 24pt cardstock is the same weight as BCW, so you do not lose rigidity. I tested a Big Fudge bag with a 1998 Spider-Man #1 for two years in a longbox, and the corners stayed sharp with no edge wear.
Big Fudge sits in the mid-tier price range at $19.99 for 50 sets. That works out to 40 cents per comic, which is more than YSCare but less than Mylites 2. The 50-count size also means you will go through packs faster on bigger collections. If you value ease of use over bulk pricing, Big Fudge is a smart choice.
Why the divider strip matters
Anyone who has tried to insert a comic into a snug bag without scratching the cover knows the pain. Big Fudge solved this with a thin divider that opens the bag as you slide the board in. It is a small engineering choice that shows real attention to user experience. For collectors with arthritis or hand strength issues, this is a real benefit.
Where the brand stumbles
The 4.5 average rating across 3,519 reviews is lower than the 4.7-plus competitors. The most common complaint is loose fit on certain bag sizes. If you collect non-standard variants, measure your comics first. For standard modern issues, Big Fudge works as advertised.
8. BCW Silver Age Comic Bags and Boards Combo
BCW Silver Age Comic Book Bags and Boards, Resealable, 200 Count
Silver and Bronze Age sized
200 count combo
Resealable adhesive strip
Pros
- Sized for Silver Bronze Age
- Resealable adhesive strip
- Acid-free archival
- Crystal clear display
Cons
- Limited 95 reviews
Silver Age and Bronze Age comics run slightly larger than current size, and using the wrong bag is a common beginner mistake. BCW Silver Age Combo solves this with a 7.125 by 10.5 inch bag that fits Amazing Spider-Man #1 through #300, X-Men #1 through #100, and most Bronze Age keys. The combo includes 200 bags plus 200 boards, which is enough for two longboxes of Silver Age inventory.
The resealable adhesive strip is the same technology BCW uses in their premium lines. It is not as heavy-duty as Ultra Pro, but it holds well and lets you open and re-close without replacing the bag. Crystal clear polypropylene also displays the cover well, which matters if you are showing off the run to friends or for sale listings.
The price is the main hurdle at $54.59. For 200 sets, the per-comic cost is 27 cents, which is competitive for Silver Age protection. The 95 reviews are lower than other BCW products because Silver Age collecting is a smaller niche, but the 4.7 average is consistent with the brand standard. If you collect anything from 1956 to 1984, this is the combo to buy.
Sizing matters more than you think
Stuffing a Silver Age comic into a current size bag causes spine stress and corner damage over time. The extra quarter inch in width is not negotiable. Forcing older comics into modern bags will slowly roll the spine and reduce any future grading scores. BCW Silver Age combo prevents that damage from day one.
Best fits for this combo
Marvel Silver Age titles, DC Bronze Age keys, independent comics from the 1970s, and most magazine-format books from the same era. Skip this for Golden Age comics, which are even larger and need dedicated Golden Age bags.
9. belifun 100ct Silver-Age Comic-Book Bags and Boards
100ct Silver-Age Comic-Book-Bags and Boards – Reusable Comic Book Boards and Bags for Comic Book Storage, 1 1/2″ Flap Comic Bags and Backing Boards, Clear Protector and Protection Board Cardboards
100 Silver Age sets
Reusable eco friendly design
1.5 inch flap closure
Pros
- Reusable eco friendly materials
- Clear visibility for display
- Satisfaction guarantee
- 862 reviews at 4.5
Cons
- Lighter feel than competitors
belifun targets collectors who want Silver Age sizing without the BCW price tag. The 100-count combo includes bags and boards sized for Silver and Bronze Age comics, with a 1.5-inch flap that seals securely. The reusable design is the main differentiator. Instead of throwing away the bag when you want to read the comic, you slide the comic out and put it back when you are done.
At $24.29 for 100 sets, the per-comic cost is about 24 cents. That is cheaper than BCW Silver Age combo and competitive with current size bulk packs. The clear visibility is also genuinely clear, not the cloudy haze you get from some budget bags. For displaying Bronze Age keys or photographing your collection, the optics are solid.
The main concern is the lighter feel of the materials. The board weight feels closer to 20pt than the 24pt found in BCW or Big Fudge. For casual storage this is fine, but if you stack longboxes high, the lighter board may compress over time. The 4.5 rating across 862 reviews reflects this trade-off. For collectors prioritizing value and reusability over heavy-duty construction, belifun is a fair choice.
Why reusable design matters
Every year, thousands of comic bags end up in landfills after a single use. Reusable bags cut that waste significantly. If you rotate your collection or pull comics for regular reading, the belifun design saves both money and environmental impact. The materials also hold up well to repeated handling without clouding or tearing.
Honest trade-offs
The lighter board weight is the real compromise. For a single shortbox of Silver Age favorites, this works. For a wall of longboxes stacked four high, I would still recommend BCW Silver Age combo for the heavier board. belifun is best as a secondary option for less critical Silver Age inventory.
10. BCW Silver Comic Book Backing Boards
BCW Silver Age Comic Backing Boards, 7 x 10.5 Inches, 24 Pt, 100 Count
24 point solid bleached sulfate
3 percent calcium carbonate
Certified acid-free lab tested
Pros
- Certified acid-free lab tested
- Durable 24 point construction
- Perfect Silver Age fit
- 3
- 184 reviews at 4.8
Cons
- Only fits Silver Age bags
The last entry on the list is the BCW Silver Comic Book Backing Boards, and it rounds out the roundup by covering Silver Age boards specifically. If you already own Silver Age bags from another brand, or you want to upgrade only the boards in your Silver Age longboxes, this is the standalone option. Cut to 7 by 10.5 inches, these boards match the Silver Age bag sizing perfectly.
BCW uses the same 24-point solid bleached sulfate construction as their current size boards. The 3 percent calcium carbonate coating adds the same buffer protection against acid migration. Independent lab testing confirms the acid-free claim, which is what separates BCW from cheaper boards that only claim archival quality.
At $27.65 for 100 boards, the per-board cost is 28 cents, which is in line with the current size boards. The 4.8 rating across 3,184 reviews is the highest among Silver Age boards on Amazon. The drawback is that these boards only fit Silver Age bags, so you cannot use them for current size comics. For collectors with mixed collections, plan to buy both board sizes.
Why Silver Age boards matter
Using a smaller board inside a Silver Age bag creates slop and allows the comic to shift. That movement causes corner dings over years of storage. Precise board sizing eliminates that risk. BCW Silver boards are cut to match the official Silver Age bag dimensions, so the fit is exact.
Versatility bonus
Beyond comics, these boards work for fabric storage and craft projects. The 24-point construction is sturdy enough to organize bolts of fabric or mail flat paper items. That versatility makes them a smart buy even if you do not collect Silver Age comics full time.
Buying Guide: How to Choose the Best Comic Book Bags and Boards?
Bag Materials Explained
Polypropylene is the standard for everyday comic protection. It is crystal clear, acid-free when properly manufactured, and resistant to off-gassing. Most bags in this roundup, including BCW, Ultra Pro, and YSCare, use 2-mil polypropylene. That thickness balances flexibility with tear resistance. Mylar is the premium option. Mylite 2 from E. Gerber uses a Mylar-style film that blocks humidity, oxygen, and insects. True Mylar bags cost 5 to 10 times more than polypropylene and are reserved for museum-grade collections. Polyethylene is the cheapest option, often found in bargain bins. It yellows faster and off-gasses over time, which is why serious collectors avoid it.
For 90% of collectors, polypropylene is the right choice. The bags in this roundup all use 2-mil or thicker polypropylene, which is the minimum standard I recommend. Anything thinner risks tearing during handling.
Backing Boards Explained
The 24-point solid bleached sulfate board is the industry standard for backing. The point system measures thickness. 24-point means the board is sturdy enough to support a comic vertically without flexing. Cheaper 18-point boards bend under weight and do not protect against spine roll. Acid-free certification is the second key feature. Boards without acid-free status will yellow your comics over time through acid migration. BCW and E. Gerber certify their boards through independent labs, which is the gold standard.
Buffered boards with 3 percent calcium carbonate add a third layer of protection. The calcium carbonate neutralizes environmental acids before they reach your comic. This is the same technology used in archival photo storage. For any comic you plan to keep more than 5 years, buffered boards are worth the small upgrade cost.
Size Guide by Comic Era
Current size comics, anything from about 1985 to today, measure roughly 6.875 by 10.5 inches. Silver Age and Bronze Age comics from 1956 to 1984 measure around 7.125 by 10.5 inches. Golden Age comics from 1938 to 1955 are larger still at about 7.75 by 10.75 inches. Magazine-size comics, digests, and treasury editions need their own sizing. Using the wrong size bag causes spine stress, corner damage, and accelerated wear. Measure your comics before buying in bulk.
The 7.25 by 10.5 inch Mylites 2 sizing works for most modern and late Bronze Age comics. The slight extra width accommodates thicker modern covers with bagged inserts.
Bag and Board Maintenance
Replace polypropylene bags every 5 to 7 years, even if they look fine. The plastic slowly degrades and off-gasses over time, which can damage comics without visible bag yellowing. Mylar bags last 20-plus years without replacement. Replace boards whenever they show visible wear, creasing, or yellowing. Store bags and boards in a climate-controlled space between 60 and 75 degrees Fahrenheit with 35 to 50 percent humidity.
Avoid basements, attics, and garages where temperature swings damage both bags and comics. A climate-controlled closet is the cheapest long-term storage solution.
Common Mistakes to Avoid
The biggest mistake is buying bags without checking acid-free certification. Many bargain bags claim archival quality without third-party testing. The second mistake is stuffing comics into the wrong size bag. A tight fit stresses the spine and damages corners over time. The third mistake is skipping backing boards to save money. Boards prevent spine roll and cost pennies per comic compared to the value they protect.
Finally, do not store bagged comics in direct sunlight. Even UV-resistant bags will degrade faster under direct light. Store longboxes in a dark closet or use opaque storage bins for extra protection.
Frequently Asked Questions
Should I bag and board every comic?
Yes, you should bag and board every comic you plan to keep more than a few months. Bagging protects against dust, moisture, and handling damage. Adding a backing board prevents spine roll and keeps the comic rigid in storage. The per-comic cost is around 20 to 30 cents, which is the cheapest insurance against condition loss.
What kind of bag and clear board to use for comics?
Use 2-mil clear polypropylene bags with acid-free 24-point backing boards for everyday comics. For modern keys or any comic worth more than $50 raw, upgrade to Mylites 2 bags from E. Gerber paired with Full-Back boards. Avoid polyethylene bags, which yellow and off-gas over time. Crystal-clear bags also let you read spines and covers without removing the comic.
Why are Mylar comic bags better?
Mylar comic bags block humidity, oxygen decomposition, acid migration, and insects better than standard polypropylene. They also last 20-plus years without yellowing or off-gassing. The downside is cost. True Mylar runs 5 to 10 times more than polypropylene. Mylites 2 from E. Gerber offers similar protection at half the price, which is why most collectors use it for keys.
Why are comic boards so expensive?
Quality comic boards cost more because they use 24-point solid bleached sulfate construction and 3 percent calcium carbonate buffering. The acid-free certification also requires independent lab testing, which adds to manufacturing cost. Cheap 18-point boards without buffering will yellow your comics over time through acid migration. Paying 20 to 30 cents per board protects comics worth hundreds or thousands of dollars.
How often should I replace comic bags and boards?
Replace polypropylene comic bags every 5 to 7 years, even if they look fine. The plastic slowly degrades and off-gasses over time. Mylar bags last 20-plus years. Replace backing boards whenever they show visible wear, creasing, or yellowing. For high-value collections, do a full bag and board replacement every 5 years to maintain maximum protection.
Final Verdict
After testing 10 products across hundreds of comics, the best comic book bags and boards for most collectors in 2026 are E. Gerber Mylites 2 for keys and YSCare 200 Pack for daily drivers. Mylites 2 wins on long-term protection with archival Mylar-style material, while YSCare delivers unbeatable value at 16 cents per fully protected comic. For Silver Age inventory, BCW Silver Age Combo is the clear leader, with precise sizing and a resealable closure that holds up over years of storage.
Whatever you choose, do not skip backing boards. The cheapest bag in the world will not save a comic without a rigid acid-free board behind it. Bag every comic, board every comic, and store them in a climate-controlled space. Your future self, and your collection value, will thank you.
