The Cast Key is one of the long-selling puzzles among Hanayama's Cast Puzzle series. Moreover, Hanayama have created a new version of this puzzle emphasising style and precision, Cast Key II. 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.
