The BCW Graded Card Bin is a premium version of the cardboard, 2-row Graded Shoe Box. Instead of corrugated cardboard, Card Bins are made from durable, acid-free plastic. These Card Bins have a pair of hinged lids that fold over the sides when open. When closed, latches keep the lids shut and cards secure. Graded Card Bins are stackable with feet on the bottom that rest in the lid of the bin below it to prevent sliding. The rows in the bins are notched along the top to hold separating partitions. Two Graded Card Bin Partitions come with each Graded Card Bin while extra partitions may be purchased separately. The card bin also comes with a pair of BCW toploaders that fit into special, exterior slots to help mark the contents of each row. The recessed handle is easy to use and hides when not needed. These are designed to work with most grading companies, such as (but not limited to): Professional Sports Authenticator (PSA),Beckett Grading Services (BGS), Sportscard Guaranty Corporation (SGC), Certified Sports Guaranty (CSG), and Hybrid Grading Approach (HGA). Additional Graded Card Bin Partitions are available separately.
