The YuXin Mirror Blocks is a popular 3x3x3 shape mod in which the dimensions of the pieces determine where it must go in a solved state. This allows it to achieve many weird shapes and makes putting it back together a unique challenge. It comes in a nice protective plastic case.

The Pink and Blue versions of the YuXin Mirror Blocks do not feature any stickers. The Black (Silver) version features black plastic and silver stickers, while the Black (Gold) version features black plastic and gold stickers.
