The deck has shrunk to half its size! This mini deck is now spread both face down and face up showing it to be quite ordinary. The mini deck can now be used in your next effect if you desire. Completely mechanical, no sleight of hand, no magnets, no elastics, perform in short sleeves. Resets in seconds--great opener--complete with mini Bicycle® deck &gimmick.
