We are pleased to offer these smart and handy, serial-numbered, plastic tamper-proof locks. These are one-time use, disposable locks. 10 units to a pack.
When one of our chastity devices, such as the CB3000, CB6000, or The Curve is locked with a plastic lock, the device will not set off metal detectors in airports or at other security checkpoints. So it is possible to wear the device 24/7 without interfering with travel or business routines.
The serial number assures that the plastic lock you started with is the same one you are wearing when the chastity device is removed. In other words, this ensures no "cheating," by snipping off one lock and replacing it with another!
