Stainless Steel Type

The crescent moon lock is named because its key is semicircular, like a crescent moon. Because the key radian (i.e. crescent moon) of each crescent lock is different, other keys with different shapes cannot be inserted into the lock hole. At the same time, the crescent moon key also changes the direction of force to unlock, so it is difficult to open.

The key is as beautiful as a crescent shaped key, which is difficult to be opened by technology and has the characteristics of multiple password combinations.
