Windmill cube shape mod speedcube fromYJ.

The YJ Windmill Cube is a neat-looking shape modification of a standard 3x3. Arranged in a certain way, it resembles a windmill. Turns smoothly right out of the box.

Argue among yourselves about whether it's a 3x3x3 or not, I can't decide! A very cool and essential addition to any cube collection though.
