Pro Shuffle automatic 1 to 6 deck shuffler. Bicycle cards are the only brand we recommend and must measure 3.5 X 2.5 inches. The unit shuffles cards the best Face Up. Smaller cards like UNO, 5 Crowns, Skip Bo or bridge size (2.25 X 3.5 inches) and cards in board games will not work. Works best plugged in. It has an ON/OFF switch. Custom Silver Wrap for a better look. Because of its design, cards come out of the shuffler much easier. Includes the Shuffler, weights, power cord. Batteries not included.
