New BCW semi-rigid #1 - 14 inch cardboard storage box. This box holds about 350 loaded #1 semi-rigid card holders. The cards are stored standing up vertically. These high quality boxes are constructed of white corrugated paper and have a 200 lb. test strength. Great for storing baseball cards, basketball cards, football cards, Magic The Gathering, Yu-Gi-Oh, Pokemon, and others. Check out my store for other card supplies, Beckett price guides and vintage trading card packs. Thanks for shopping with Back-When-Collectibles.
