Standard trading cards are 2 1/2” x 3 1/2”, but cards of smaller sizes exist. In fact, the original trading cards were smaller than this at about 1 5/8″ x 2 3/4″. A major issue facing anyone collecting these “mini” cards is the simple fact that most supplies are designed for cards significantly larger. Everything from boxes, sleeves, binder pages, and card holders are too large for safe use. However, BCW produces LaserWeld Card Insert Sleeves for these smaller cards. A U-shaped pattern is laser-welded into the center of thick polypropylene sleeves, which creates a pocket to center the mini card in a 2½” x 3½” form. The card is placed in the pocket, and then the sleeve can be placed in any standard Magnetic Card Holder, LaserWeld 9-Pocket Page, or other storage solution.
