Very beautiful and also well turning Sqare-1 transformation. This is so far (I know) Kyler's first SQ-1 based puzzle. While from the technical complexity it is not more difficult than a normal Square-1, the flat pieces make it a little bit more confusing. As it is of perfect quality again, it is really a gem with carefully chosen and arranged colours.
Size: edge-to-edge 7cm. rhombus diameters: 5cm and 3.5cm, edges 3cm
