I bought a half dozen of the Hanayama cast puzzles of varying difficulties. All of them are very well manufactured and finely tuned for exacting performance and results (which haha, can be frustrating!). Putting them back together is just as challenging so each puzzle is really two separate puzzles. If you love jigsaw puzzles, crossword puzzles, Sudoku, and other puzzles, you will love solving these.
On another note, working with AreYouGame.com was easy, quick, and professional - from the online experience, to delivery. Very well done!
