【Cultural and Creative Product】Full House of Gold and Jade – Pull-back Lock

NSTM collects over six hundreds of ancient Chinese locks. There is a lock with special design that the keyhole of such a lock is actually a seam between the lock-body and the sliding bolt. The key is a thin piece of elastic metal. The key is inserted and pushed until hearing a clack. Then, it is unlocked by pulling the key back. Such a lock is named “pull-back lock” and for the motion of opening. It also shows the clever designs and exquisite skills of ancient locksmiths.
