I recently bought the Mopin Puzzle off of cube4you.

The puzzle arrived fine in a very nice tin and everything.
I was just wondering if anyone else has bought this puzzle, and if so, has completed it.
There is only 1 site on the internet on it, and all of it is in Japanese.
The objective is to take the 52 pieces and create 2 cubes, with sides of 7 units long in measure.
I've found this very difficult, but a fun challenge.
