We have been selling this trick in our London shop for many years, and during that time the quality has varied considerably - some being so poorly made that we simply binned them. This model, I'm pleased to say, is one of the far better quality in both finish and working. 

The effect is as follows, the Magician shows a small cardboard box, containing 6 dice. Each dice has the individual number showing at its face, the box being of a size that doesn't allow any of the dice to move. The box is closed with its lid and a 7th dice is introduced, the new dice is rolled onto the top of the lid and the face number is noted. The lid is now removed and all six dice are now showing the same number as the rolled dice.

It's easy to perform, can be left for examination and re-sets quickly. An ideal pocket tick to carry around ready to perform anytime.
