Effect : A solid metal die is place in an opaque metal box, and handed to the performer behind his back. The performer reveals the number on top of the die.
Although similar to items like Color Vision in effect, this is miles ahead in method - the performer does not bring the box to the front, or secretly look into it. There is no guess work or ambiguity about the number - the performer reveals the number that is on top.
The props are precision machined in solid brass, and for those that want super quality props, and clever methods, this is one of the best. Not cheap, but for those that value quality, this is excellent value. Complete with instructions, ready to use, with just a few handling trials.
