The great "Passe-Passe" effect with two beautifully made, flat plastic dice. One has a 4-spot on top, a 3-spot underneath; the other a 5-spot on top, a 2-spot underneath. Magician explains that the opposite side of each of the die totals seven. Quicker than a wink, the dice change places over and over again. No shells, magnets, sliding parts, etc!
