Item Number: RO2812
The ultimate transposition!
A penny and a washer are displayed. The penny is placed in a small black box. The washer goes into the magician's pocket. After opening and closing the box, the penny and washer are shown to have exchanged places.
A clever principle does all the work for you. The penny and washer can exchange places as many times as the magician desires.
No sleight of hand required.
