Effect: Five different colored keys are placed in a strikingly beautiful antique, hand-crafted, gold inlaid brandy snifter and passed through the audience. Four members freely select a key, leaving one for the performer. Keys may be exchanged among spectators and performer. Finally, one key remains in the goblet, this key going to the performer.

The spectator's each try their key to no avail, the performer's key is now inserted and it OPENS the lock!

It's a reputation-maker. To be sure, some marvelous versions of this effect exist on the market today. Some rely on batteries and radio transmission. Others have incorporated locks that were well-gimmicked, but were small and insubstantial, as compared to the spectacular effect. This lock is a world-beater. No electronics, no switches of any kind. It is one hefty piece of work weighing almost two pounds. It is a heavy, polished chrome padlock of imposing construction. And, when it opens, at the peak moment of dramatic tension, it literally 'springs' open with a resounding snap!

Comes complete with keys, lock and detailed instructions. Use your own brandy glass.
