This Rubik's Cube is the perfect puzzle for anyone who likes a challenge. The cube is made of high quality plastic. This creates a visual effect that makes the cube appear to be made of reflections. Because the colors are the same, it's hard to tell which side is which. This can lead to errors that can make it difficult to solve the cube.
