Whether you're looking for a gift for a collector of sports cards or wanting a place to store your own collection, the UniKeep baseball themed card storage binder is a great choice. This kit includes 10 platinum series collector sheet protectors made by EnvyPak. These included sheets will store up to 180 standard sized cards. If your collection continues to grow this binder has room to comfortably hold 500 or more cards (with additional card protector pages). The UniKeep binder features snap-locking poly rings that make adding and removing sheets safe and easy - even for small children. The UniKeep enclosed binder is unique because it is a fully enclosed "box". The binder and the archival pages will protect your cards from dirt and dust so their value is never lost. Like all UniKeep Binders, the Card Storage Binder is made and printed in the USA. The included pages are also made in the USA.
