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 & 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.
