These black locks from Shots Toys are a must-have for anyone fancying chastity play. The locks feature individual serial numbers, which is very useful when locking chastity belts – the numbers ensure that the wearer is wearing the same lock they started with. So if you catch the wearer cheating, you have to sanction them...

Because the locks are plastic, they can also pass through metal detectors at airports, etc., along with non-metallic chastity cages.
