Whether you're looking for a gift for a collector of sports cards or wanting a place to store your own collection, the UniKeep football themed card storage binder is a great choice. This kit includes 20 platinum series collector sheet protectors with the metal ring version (the poly ring version comes with 10 pages). These included sheets will store up to 18 standard sized cards per sheet. The UniKeep binder features standard sized metal binder rings that make adding and removing sheets safe and easy. 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.
