Object: Separate the two pieces and reassemble. Note: Our level rating system is different than Hanayama's. Hanayama's level 1 is equivalent to our level 5.... level 6 is equivalent to our level 10. This puzzle has a Hanayama rating of 6 out of 6. The latest addition in the Hanayama series! The stylish design of the matching interlocking pieces of the Cast Rotor display like an emblem. The uniquely cut pieces, along with the fact that there are numerous solutions, make this a difficult puzzle. Designed by Hong Kong designer Kyoo Wong.
