This is a box or case that apparently holds two decks of Bicycle cards, one red back and one blue back. It will permit you to change the deck of Red backed cards in a very easy manner right under audience view. You can change your examined and shuffled deck for a set-up deck, or any other special deck. This looks like a "book" in a wooden finish, with velvet lined compartments for the performer wanting a superior quality prop.
