Kennard's Mystery Box by Daytona Magic, Inc. First sold in the mid 1960's. It was a tiny box made by D. Robbins. A ton of them were sold but alas it disappeared. Kennard came across an old instruction and decided to make it bigger and better. The gimmick is stronger and better hidden. The ring is larger. The box is made from solid oak and treated with Tung oil. Dimentions Approximately 3.5" x 4"..
