Fully adjustable to ensure the perfect fit, these unisex contrast colour cuffs measure between 7.5 inches and 11 inches in circumference when fastened. They are ideal for bondage beginners, and make a comfortable alternative to heavy metal handcuffs. Each cuff has two nickel-free metal D-rings to clip the included connecting chain to, leaving one free at each wrist to attach to bed restraints, tethers, collars or ankle cuffs - the options are limitless. Composed with sturdy stitching and strong metal fastenings, these cuffs are incredibly durable and are able to withstand plenty of resistance, meaning you'll only have to be as gentle as your lover wants you to be.
