Inside the box, there was extra spring and cube. At first, the cube was covered with lube. But after I cleaned it, It was really quiet and corner cut almost everywhere. Its feeling is unique like smooth but scratchy that I could just say 'dayan feel.' It has glossy finish, primary internal, and slightly small size. Also, it is super fast(which I like it). If you like fast, smooth, quiet, and flexible cube, go for this cube.
