3x3x3 Mirror Cube

The 3x3x3 Mirror Cube, Mirror Cube, Bump Cube, or Mirror Blocks is a shape modification of the Rubik's Cube invented in 2006 by Hidetoshi Takeji. The puzzle is in the shape of a cube with all pieces being distinct rectangular prisms having the same color, typically reflective silver or gold. As the puzzle retains the 3x3x3 shape of a Rubik's Cube, they can both be solved in the same way, albeit it is more difficult to match pieces to their respective locations due to the lack of identifying color and disparate piece sizes.
