These little black beauties are not meant for heavy BDSM play. Instead, they are meant for every day wear or as an accessory to an outfit. The cuffs are on the small side, so I highly recommend measuring your wrists before purchasing. This cuff set also comes with a chain, so you can wear the cuffs seperately or attached together. The black beads shimmer and shine in the light, and they are absolutely gorgeous when on the wrist.
