This is a 2x2x1 custom Rubik’s cube.
It is made from 4 mini Key-chain Eastsheen 2x2x2s.
The 2x2x2s cost me under $3 a piece (not counting shipping) from Omega Studio Cube shop on ebay: http://stores.ebay.com/OMEGASTUDIO-CUBE-SHOP
The stickers cost $1.25 from cubesmith.com They are Eastsheen 2x2x2 sized stickers.
To build this puzzle, I followed the instructions from this video:
