Designed & made by the Karakuri Creation Group in 2004. The group themselves consider this to be the most difficult of their first 3 releases in the series. They even give this clue "There is the answer on this plate." Cryptic? for sure! Any help to solve? not sure! Once you know the solution you can open it in just two moves. But one of them is quite a unique movement so don't be fooled that that makes it easy to open!
This very special puzzle box is crafted in Katura wood (a type of Cherry tree).
Size outside: 42mm x 42mm x 60mm Space inside: 31mm x 17mm x 24mmA solution is provided.
