Padlock*****

hanayama puzzle-Cast Padlock by Hanayama is exactly what you’d want your average puzzle look like. It’s a padlock that you need to unlock and if you think it is as easy as that — you’d be very wrong. Channeling your inner Arsene Lupin will not be remotely enough. The mechanism of the puzzle requires a good deal of spatial awareness and imagination to resolve.Source: https://puzzlescore.com/en/hanayama-huzzle-cast-padlock
