Perky Penny by Royal Magic

The ultimate pocket transposition. A penny and a metal washer are openly displayed. The penny is placed inside a small black box. The washer goes into the magician’s pocket. With a simple open and close of the box, the impossible happens. The penny and washer have switched places.
A clever mechanical principle does all the work. The exchange can be repeated again and again, each time more baffling than the last. No sleight of hand is needed. Everything is simple, direct, and astonishing.
Complete with all necessary props. Made in the USA by FUN Incorporated.
