When your foray into bondage become really serious, not just any handcuffs will do. Something strong and secure is in order for the games you play. Supercuffs by Sportsheets are as strong as leather, with the comfort of neoprene, and the security of double locking Velcro straps and large welded D-rings. The wide bands adjust to fit most wrists or ankles. Use Supercuffs with Sportsheets tethers or other bondage hardware.
