9 Acid-Free Storage Solutions for Your Comics

Image source: Amazon

Did you know that there are systems and levels when it comes to acid-free storage solutions for comic books? First of all, you should be using only acid-free sleeves, backing boards, display cases, top loaders, and storage boxes to protect comics. Also, you should nest each product into another, with proper sealing, to optimize protection.

Older comic books were made from the cheapest paper stock. Such vintage paper degrades quickly after exposure to the elements. So, you can place a comic book into a sleeve with a backing board, then into a top loader, and then into a comic book storage box. If each of those products features an acid-free coating, then the comic could last a lifetime.

What makes such products “acid-free” is the fact that they feature a coating of 3% calcium carbonate. Calcium carbonate absorbs and neutralizes the acids and compounds that naturally degrade paper. 

Here are nine acid-free storage solutions for your comic books.

1. Cardarchiver UV Protection Slab Protectors (2-Pack)

Magnetic comic book display cases are a very underrated form of acid-free storage solutions. A magnetic display case, or slab protector, is a translucent acrylic enclosure that protects your comic. This one is meant for wall mounting. 

The casing features UV protection and protects comics from fading and yellowing from sun exposure. Here are the dimensions of the product: 6.625 x 10.25.

These display cases also feature magnetic enclosure points. They keep the casing locked and protect your comics from dust, moisture, and the elements. This product is optimal for use as all mounting but can also be displayed on wall units or desks. Only insert Modern Age comics into these display cases.

2. Big Fudge 50 Comic Book Bags and Boards (50 Sleeves and 50 Boards)

The sleeves are 3-mil thick. This is an archival-quality product. So, if you insert your comics and seal them properly, then they could last for a lifetime.

Acid-Free Storage Solutions

Did this article seem overwhelming? That was not the intent. However, if you want to protect your comic books, this is what you must do. It takes a lot of time and financial sacrifice, and physical effort to organize a large comic book collection.

Still, I would recommend that you only resort to such efforts for valuable comic books or old comics with sentimental value. Any comic book could rise in value, but most don’t. You should know which comics in your collection are more valuable relative to others. However, every comic in your collection may not warrant such levels of protection.
