Merriss Magic original Key R Rect Master Lock Trick

This is the one that similar, and usually lesser quality, tricks have been fashioned. This is the Merriss Magic version. Original, and real, Master brand lock with Master Lock marked keys as well. Original Plastic case and 10 page instructions also included.

Instructions list multiple tricks and there is a lot you can do with this setup. Basic premise is that a large number of keys are shown with a lock and it is proved that only one of those keys will open the lock. The spectator(s) is allowed to check all of the keys prior to somehow mixing them up or placing them in matching envelopes. The magician then mentally or otherwise determines which key is the single one that will open the lock. Great thing is that once the performance is done all the other keys can be checked and they do not open the lock. Lesser new sets that usually don't look authentic/real to me run close to opening bid but this set is THE set.

Everything is like new though lock could use a little suggested drop of oil for smoother operation. Plastic case has some surface cracks but solid.
