So you've played around a little (or a lot) with restraints and cuffs; this pair of Professional Police Cuffs is a step up. Most wrist cuffs for sex play have a quick release tab on each cuff so they can be removed quickly, by either the wearer or receiver. These do not. The Police Cuffs are the real deal . They lock and unlock with a key, and that's it, so once your playmate is cuffed up, the only way they're getting free is by you and you alone. These cuffs are sturdy, solid and almost indestructible, they're perfect for rougher play. Fit most.
