Hone your safe-cracking skills with this pseudo-combination lock. The five metal pieces must be twisted, pushed and pulled in the perfect sequence in order to come apart. Upon first examination, it may not seem possible, but just like a jewel thief at a bank vault, if you listen carefully, you may discover a clue to the hidden mechanisms inside.

Designed by master puzzle inventor, Vesa Timonen from Finland. The same devious mind that brought you the Loop, Keyhole and Donut pocket puzzles. Produced by Hanayama of Japan.
