Heat-Sensitive Black Rubik's Cube for Advanced Players

Warm colors for an all-black cube. Play blind or almost with this very special 3x3 cube. Completely black, the colors of the squares are revealed by the warmth of your hands but disappear quickly. Will you take on the challenge of playing without seeing the colors? The secret of this very strange cube lies in its thermochromic technology. It is entirely black and only reveals its colors through heat, only in the places where you touch it. As soon as the colors are revealed, they start to fade and disappear if you no longer touch the area! As curious as it is attractive, it represents a real challenge for seasoned players or cube fans.
