Ultra PRO’s original clear Soft Trading Card Sleeves are made with non-PVC, archival safe, and acid-free polypropylene film. These sleeves protect your valuable trading cards and collectible game cards from dust, dirt, and natural oils from your hands during handling and storage of the cards. Designed to hold standard size (2-1/2″ X 3-1/2″) trading cards up to 35 points in thickness, these sleeves also minimize surface scratches on your cards during sorting, display, or, for gaming cards, during gameplay.
