The okito box is a cylindrical box fitted to the size of a coin, used to perform coin magic. Invented by Tobias Bamberg, better known by the Stage name Okito, a coin placed in the box seems to vanish, appear and penetrate the box.
Some magicians think that the box itself is so esoteric that it has no purpose. However people like David Roth, Mike Gallo, Chad Long, Chastain Criswell, and Paul Cummins have great routines. Chastain Criswell also uses a production of the box itself in order to make the prop less a prop and more a necessary container.
