Penetration Frame (Royal)

This latest type of frame is made of plastic so it eliminates the hazard of glass breakage. A piece of clear plastic glass mounted in the frame can be critically examined both before and after the trick. Cards are fastened to each side by means of clips which are a part of the frame and the wizard then thrusts a pencil and other objects like a silk through the center of the cards and glass. The cards are removed and examination of the glass fails to disclose any hole.

Extremely ingenious.
