The magician allows the audience to examine a case that is divided into three compartments. The spectator then inserts three metal bolts, and screws them into place. Before locking off the end bolt, the spectator is instructed to link a finger ring onto this bolt. A clear cover is slid into place, making it completely impossible to touch the ring from outside the case. However, simply covering the case with a handkerchief, the ring magically flies so that it is linked onto a different metal bolt. Includes instructions. Very good condition.
