Katomula Black Matte Card Sleeves 300 Pack - Standard Size 66x91mm, Non-PVC, Edge-Tear Resistant
These Katomula Black Matte Card Sleeves come in a 300-count pack, sized at 66x91mm to fit standard trading cards like Magic: The Gathering. The sleeves feature a clear matte front for smooth shuffling and a fully opaque black textured back that hides card backs. Made from acid-free, non-PVC polypropylene, they resist edge tearing up to 58N, helping keep your cards protected from dust and moisture.
Sizing and Fit
Each sleeve measures 66x91mm with consistent cutting, fitting most standard-sized trading cards. This includes MTG, Pokemon, and many collectible card games. For sports cards or other cards slightly smaller than 66x91mm, the sleeves will accommodate them with a bit of extra room. The pack contains 6 decks of 50 sleeves each, giving you 300 total sleeves to sort multiple decks or share with friends.
Shuffling and Handling Experience
The matte textured back provides a comfortable grip that feels secure in your hand. When stacked, the sleeves don't stick or slide, making riffle shuffling and pile shuffling smoother. The clear matte front reduces glare while still displaying the card art clearly. Many players prefer this texture for long sessions because the sleeves stay in place and don't become slippery with use.
Are These Sleeves Safe for Long-Term Card Storage?
The sleeves are made from polypropylene with no PVC and are acid-free. This means the sleeves themselves won't break down or release harmful chemicals that can damage your cards over time. The opaque backing also blocks light and helps shield cards from dust and moisture. While no sleeve guarantees indefinite protection, these materials are commonly used for archival storage.
Durability and Tear Resistance
Katomula uses an edge-tear resistant design. The sleeves have been tested to withstand forces over 58 Newtons before tearing. This makes them less likely to split at the seams during intense shuffling or accidental pulls. However, like all sleeves, they are not indestructible—avoid sharp objects or excessive force.
