Take a look at our heavy-duty stainless steel handcuffs,ankle cuffs, and collars. Made of 24 ga. x 1 1/2" stainless steel. Encased in a clear vinyl in the front, and black vinyl backing. They have a built in locking system that allows them to be locked without using padlocks. These locks are so secure, they can't be picked by even the best of experts. If you order a chastity belt, the cuffs can be made to fit the same key as your chastity belts. Two keys are included with these cuffs. Extra keys are available.
