This Mirror Rubik's Cube is the perfect puzzle for anyone who likes a challenge. The cube is made of high quality plastic and is covered with a mirror layer. This creates a visual effect that makes the cube appear to be made of reflections. The mirror effect makes the cube harder to solve. 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. However, the mirror effect can also make the cube more interesting. Because it looks like it's made of reflections, it can be an interesting and challenging puzzle.
