The Cast Key is one of the long-selling puzzles among Hanayama's Cast Puzzle series. We have created a new version of this puzzle emphasizing style and precision, as PART2. Designed by Otake & Wong.
The object is to separate the two keys and then restore them to their initial state. It looks simple, but in fact involves a little trick. Beginners should therefore be careful not to pull them apart by force. Theme: "Key".
