Produce or vanish 1 - 4 coins from a single cup! By simply turning the cup over, you can pour out 1, 2, 3, or 4 coins, or vanish any number from 1 to 4! Use the Shamrock Cup for flying coin routines, coins through the table, etc. The cup is precision made in aluminum and designed for U.S. half dollars and similar size coins. Comes with detailed instructions, plus a bonus routine from Aldo Colombini.
