If you canâ€™t resist the look of traditional handcuffs, The Kinklab Double Lock Police Style Handcuffs are for you. Novelty handcuffs can pinch skin and damage nerves in the wrists by pulling too tight during play. The Double lock feature on these cuffs from KinkLab ensure that your captive stays comfortable, no matter how heavy-duty for your play. These double-lock steel handcuffs would be a great addition to your role-playing. Comes with 2 keys. Note: Metal handcuffs can still cause nerve damage, even with the double lock feature and should not be used for suspension. If you intend to keep these cuffs on for a long time, put a soft barrier (like a handkerchief or sock) between the cuffs and skin.
