This is a brand new LanLan Skewb puzzle. It is a very fluid puzzle, and can be used for speedsolving.
The Skewb moves a group of three mid-faces and four corners by rotating around the corner at the center of the group. It has precision injection molded parts with spring-loaded bearings which make operation easy and exact. Although it is cubical in shape, it differs from Rubik’s construction in that its axes of rotation pass through the corners of the cube rather than the centres of the faces. There are four such axes, one for each space diagonal of the cube. As a result, it is a deep-cut puzzle in which each twist affects all six faces.
This puzzle comes 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.
