A long solid wooden key holder is shown with a key attached by a loop of chain running through a hole drilled near to one end of the holder.  The performer can freely run the chain through the hole.

The performer then visually moves the key and the loop of chain as well as the hole to the middle of the holder.  There is now no longer a hole at either end of the holder.  The performer can still freely run the chain through this new hole in the holder.

The performer now moves the key and the chain as well as the hole to the opposite end of the holder.  There is no longer a hole at either the middle or the other end of the wooden key holder.

You receive 2 wooden key holders: a gimmicked key holder as well as a non-gimmicked one.  The non-gimmicked key holder is for you to switch at the end of your demonstration so that you can hand the key holder out for examination.

The wooden key holder is approximately 6.25 inches long and 5/8 inches wide.  As with all Mikame products, the 2 key holders are very well manufactured.

The Mystery Key Holder is the invention of Satoshi Toyoda.  The method is quite ingenious.  The illusion of the moving of the hole and chain and key from one end of the holder to the middle and then to the other end is quite convincing and visual.  (Rated 5/5 stars)
