A 7x7x7 transformed into the shape of a Reuleaux tetrahedron.

The images show the second version of the same inventor. The first puzzle of this shape has a white body. A true tetrahedron with planar faces would have become unusably big. Hence, the puzzle had to have this pillowed shape.
No later than 2020 a mass produced stickerless version from Shengshou (Sengso) hit the market.
Edge length: 100 mm
Weight: 245 grams
