Mentalists Pad by Jerry

The Mentalist Pad The quality and the design of the Mentalist pad will allow it to be freely handled and written on by your helpers. The clever construction adds to the look of being just a normal note pad, because the working parts are completely hidden out of sight. The two top sheets disappear when the cord, which is attached to the pencil, is pulled. The operation is smooth and easy to use, resetting is very easy too remember to remove the pencil from the holder first.

This is a great way to switch a written set of numbers, drawings or words completely innocently.
