Ahh, the lovely black and white leather cuffs. A mainstay of the site from the early days, we don't use these anything like as often as we used to. Which is something of a shame, as they are exquistely well designed- there is a pillar with a hole drilled in it which provides a locking mechanism with some suitably small but sturdy padlocks, the cuffs are made of soft leather lined inside with lambswool and are comfortable for very extended wear. The secure D rings allow the subject to be positioned in many different poses with minimal effort for her owner. A real design classic!
