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 PART II. Designed by Otake and Wong. The objective 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”.
