This Mirror Double Cube is made with a black plastic core and has gold and silver labels. Unlike most rotational puzzles, the object is to scramble up the shape and then return its original starting position. As denoted by the name, the Mirror Double Cube is essentially two mirror cubes fused together along one edge. This cube is extra tricky because not only can it be really hard to tell where each piece goes, but it also limits your ability to get it there. This is one of many great puzzles by Cube Twist.
