4 pc set includes: 2 wrist cuffs and 2 ankle cuffs, each 1 1/2 inches wide, with built-in 48 inch nylon tie straps. Wrist cuffs are adjustable to fit up to 8 inches, ankle cuffs are adjustable to fit up to 10 inches. This is the original cuff that pioneered soft restraints over two decades ago, and still sets the industry standard today. These are the most secure restraint cuffs we make. Made from nylon parachute webbing, chosen for its softness, strength, and durability. The VELCRO that locks the cuff is sewn leaving little tails so that it is more challenging to peel out of them, providing maximum security. The soft buckle is a braided parachute cord that is extremely strong and durable, yet won't pinch your skin or hurt you. An extra loop on each cuff provides an attachment point to fasten the cuffs together or to other accessories. Versatility: our cuffs, with built-in nylon tie straps, can be used wherever your fantasies lead you. Tie them together or tie them apart, to a bed frame, a chair, a closed door or attachment points on the wall. There is no metal in this restraint cuff set (saves embarrassment when going through security metal detectors), yet they are strong and secure. While it might be possible to work out of the cuffs, it will be a challenge; these are more secure than you might expect from a soft VELCRO cuff.
