The Dex Zip Binder 12 provides the ultimate in style and protection for your treasured collection. They comfortably hold 480 double or single sleeved cards in side-loading pockets and utilize an additional flyleaf before the first and after the last page to provide additional protection. 20 side loading acid and PVC free pages. Adorned with a heavy gauge tough zipper. The exterior is constructed with the same Saffiano exterior as our Creation Line Deck Boxes with added padding for an extra luxurious feel. We lined the inside with black velvet for that perfect soft touch. We've done away with flimsy straps and use a triple-reinforced band that keeps a tight closure to keep your cards safe!
