Lock'd In is a brass puzzle that is also a semi-functional padlock. The lock has no keyhole, no buttons or dials. You'll have to listen carefully and experiment to imagine what the hidden locking mechanism inside might look like. The solution is not as difficult as the fiendish Dan Lock and Lock'd In is also nice because once you crack it open, the cleverly engineered mechanics are in full view to admire.
Measures about 2" in diameter.
