Fancy playing Naughty Policeman?
These light, metal handcuffs are intended more for play than for serious domination; the quick release mechanism is useful in case you lose the two keys provided, but a determined detainee would probably be able to activate it, so don't rely on these to be able to restrain anybody who is actually trying to escape!
Starter Metal Handcuffs is made from steel. It's measurements are one size. Power Requirements: None Required.
