A Junior Bump Cube (aka Mirror 2x2x2) with transparent extensions. There are two solved states.
This puzzle represents two 2x2x2s at the same time which explains its name. The inner 2x2x2 is a custom made Junior Bump Cube (aka Mirror 2x2x2). Its pieces were extended with transparent plastic. These extensions were added to the inner 2x2x2 in one of its scrambled states.
This puzzle can either be solved by shape of the inner 2x2x2 (images #3-#4) or by the shape of the outer pieces (images #1-#2). Refraction at the boundaries of the transparent pieces make solving the inner 2x2x2 more difficult.
The creator also made a version with a non-uniformly stickered inner 2x2x2.
If you're looking to buy, eBay is the one place you can find almost anything... if you're willing to wait for it, then pay the price!
