Magician introduces a box that contains 4 different (shaped) punchers. (Each puncher can make a unique shape).
Ask the spectator to freely choose one of the punchers and make a hole with the chosen puncher.
Now the bottom of the box is opened, a paper that printed “?” is found.
The “?” paper is flipped over…. The spectator finds it is the same shape that he/she made a hole with the chosen puncher.
An improved gimmick made impossible possible. It allows you to show (display) the box and punchers even after performance.
NOTE: Designs and colors of punchers may vary.
