A large plex housing is shown with a currency note (the larger value denomination the better) contained within and locked in place with a padlock. One key is shown to open the padlock and all are shuffled about losing track of the key that works the lock. The keys may then be placed in envelopes or just shuffled about in a glass and one at a time spectators take their chance at picking the right key. Coming to the last key the magician reserves this for himself and of course it works the lock!

You will have to just love the principle behind this mechanical effect. Includes instructions. A couple tiny areas of patina on the brass lock otherwise condition like new.
