This is the classic toy reinvented for the modern magician.
With Super Vision Cube, you will have full control over what you want to be shown in the box. There are no electronics involved, and only one cube is used in the entire routine, which is 100% examinable at the beginning and at the end without the need for a switch.
The cube is fully customizable with the white plastic stickers included, making this a great tool for any type of performer, from serious mentalists to street magicians.
Super Vision Cube can not only be used to read minds, but also to force anything you want, as you decide what you want to be shown on the top side.
