This came from an old magician’s estate purchase. Very good pre-owned condition and comes with the original instructions.
This was a marketed item from the 1980’s and was sold through Tannen’ s Magic. It allows you to ditch a coin or small object standing up, without having to use a Topit. No jacket or sleeves required.
In Europe they’ve used a belly Servante for years. Fred Baumann’s is very much in the same concept of theirs…however it is smaller.
The thinner you are the easier it is to use.
