Non plasticized means that these coin flips contain no softeners, PVC or any other chemicals that might damage coins. As a result of the non plasticizing, these coin flips are more rigid than the average flip. Each flip has a double pocket design that is ideal for storing a coin in one pocket, and an insert in the other. The insert can be used as a display card or a miniature information sheet, and most flips come with inserts. Each non plasticized coin flip is made from materials that are safe for long term storage. We also have a full line of coin pages and storage boxes made to hold coin flips.
