Invented by Pro-Mold in 1991 (U.S. Patent 5,224,600), the mini-snap is a two piece snap design card holder that is ideal for inexpensive trading cards. The mini-snap was the first baseball card case to fit into the standard set storage boxes (pictured above) allowing you to keep complete sets in place with the most expensive cards being preserved in this holder.
Strengths: Inexpensive. Small and compact which allows for storage of many in smaller spaces particularly in standard set storage boxes that hold complete sets of collectible cards from trading card manufacturers like Bowman and Topps.
Product Type Snap Case
