The Mf8 Teraminx is made from a high quality black ABS plastic. The idea of this puzzle is to scramble up all 12 sides and then return it so that each face only has one color on it. This puzzle is extra hard because each of the 12 faces has 5 edges, and each edge is 7 pieces across. MF8, the creators of the Tertaminx, is owned by Mr. Fok, who is not only a designer, but also owns an OEM factory, which allows him to continually release puzzles into the market.
