Crunch (Trò lừa) - Món đồ cho ảo thuật gia

Magicians' gimmick.

Crunch is my take on a joint-cracker. Designed for easy palming and ditching, you can hide, transfer and get rid of it easily in your finger-cracking and wrist-cracking routines. You'll need a printer that is capable of printing dents and gaps. For printers that print thicker walls, you may need to grind the screw and the inner part of the nut manually.
