Good used condition with English / Spanish instructions.
I find this concept very clever; four spectators are given a chance to win a price. All they have to do is pick the correct key out of five that opens the lock of a wooden box. They all try and fail. One key remains for the magician, he asks another spectator to try this on his behalf and his key opens the chest.
No electronics, no complicated work by the magician. Please note that the magician never touches the chest nor the keys. Everything can be handled by the spectators. There are no key switches, or partially inserted keys!
Long unavailable and difficult to find. The interior mechanics are impressive, and I have not seen this principle applied. Tested and functioning perfectly! The box is 8×5.5×4 inches.
You receive 5 keys for performance and 1 spare (there are usually 2 spares but one is missing – not needed for performance), the clever chest, reset tool and detailed instructions. At one point there might have been a velvet carry bag, but I do not have that.
