Why would anyone use PVC holders for their valuable collectables when SuperSafe has these superior polyester holders. (The duPont folks call them mylar.) SuperSafe durable holders provide archival protection at an affordable price. Don't be fooled with phrases from PVC holder manufacturers like "free of chemical softeners and stearates" - ALL holders made from PVC - even those that are softner free - are not acceptable for storing valuable collectibles. SuperSafe Prolar polyester holders are!
These holders are open at the top for easy insertion. They are available in packages of 10 or 100.
