From the publisher:
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. 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. The theme is "key." Designed by Otake & Wong.
Hanayama is known worldwide for challenging puzzles and quality manufacturing. Can you take the pieces apart, then put them back together again? Hanayama cast metal brain teasers have 6 levels of difficulty, and each puzzle is Mensa-rated. Level 2 puzzles are considered fairly easy by most puzzlers. BePuzzled is the exclusive distributor of Hanayama Cast Puzzles in the USA.
