Holding the wrists and ankles of your partner tight in playful captivity, the Wrist & Ankle Restraint Kit was designed with serious fantasy fulfillment in mind. 2 sets of cuffs are spaced out around a sturdy metal ring, they're soft but extra sturdy and user friendly, closing with simple Velcro. You can bind up the arms and legs of your playmate in any combination, or strap him or her to yourself, if that's your cup of tea- the cuffs have lots of room for adjustment, making them perfect for almost any size. The 1.5 inch (3.8cm) O-ring at the center provides an anchor for any compatible restraint system or leash that you might want to add into the equation. Hardware is nickel free.
