|Free the Key|
It is a pretty big puzzle measuring 11cm long with the disk being 4.5 cm diameter and a very decent weight. It feels fantastic in your hands. It consists of a very large key with protrusions of varying height on either side and a brass disk at the hilt of the key. The disk has slots cut in it of varying heights to take the protrusions. Overall this is a good quality puzzle - the finish is not quite as good as the Hanayama puzzles (there are some casting marks on the key and the brass disk would be nicer with a glossy finish). I think this is pretty good value for money - you get a decent bang for your buck.
