Take your cubing skills to the next level with the 3x3 Mirror Blocks Cube (also known as the Bump Cube). Unlike a traditional Rubik's cube with colored stickers, this mind-bending puzzle features a uniform, high-gloss reflective silver surface.The real challenge begins when you twist it: every single piece is cut to a different size and thickness. As you scramble it, the cube morphs from a perfect square into a chaotic, spiky, and unpredictable 3D geometric sculpture!
