This is a brand new Shengshou Mirror Blocks puzzle. It is similar to a standard 3×3 Rubik’s Cube, except instead of colors, each piece is a different size. All the stickers are silver color, but the pieces are all different sized rectangles. It makes for a very fun and challenging brain teaser (see scrambled photo).
This puzzle comes fully assembled and stickered from the factory. Note that lubricating and working in the cube improves its performance. It is highly suggested to lubricate the cube to make it move more easily.
