This Siamese Mirror Cube is made with a black plastic core and gold labels. Unlike most rotational puzzles, the object is to scramble up the shape and then return it to the normal rectangular position. As denoted by the name, the Siamese Mirror Cube is essentially two mirror cubes fused together, so that the overall shape is a 3x3x7. The Siamese Mirror 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.
