These single use, numbered plastic chastity locks are ideal for keeping tabs on a naughty plaything. Each lock is designed to be tamper evident; any attempt to remove the lock will destroy it. Functionality similar to a zip tie, these locks are easy to put on but require scissors to be removed. Each lock has a unique number, allowing the "keyholder" to easily identify the correct lock. The plastic material is ideal for polycarbonate or plastic cages, which will not set off metal detectors. Lightweight and water safe, these numbered locks can be removed by the wearer if the need arises. Material: Plastic. Color: black. Note: comes with 10 individually numbered locks. Chastity devices sold separately.
