Ultra Pro PRO-Fit Standard Inner Sleeves – 100-pack

PRO-Fit is Ultra Pro's series of inner sleeves for standard-size cards, such as Magic and Pokémon cards. The sleeve fits tightly around the card and is then placed inside a regular sleeve, so the card gets two layers of protection. The pack contains 100 sleeves.

Ultra Pro states that the sleeves are made of ultra-clear, archival-safe and acid-free polypropylene. They can also be used on their own when the card's artwork should show without a border, and Ultra Pro recommends them in a One-Touch 35pt for cards that are taken out and put back often.

PRO-Fit is also available in a side-loading version. Dragon Shield's equivalent is called Perfect Fit. A regular sleeve goes over an inner sleeve, and a card for display can then be placed in a One-Touch 35pt.

They work well for players who double-sleeve a deck and for collectors who want thin protection inside harder storage. Ultra Pro advises against using them on sports cards with sharp corners, as the tight fit can damage the corners.
