Nukkles are made of a flexible polycarbonate material that permits them to contour to each individual's body for the ultimate relaxation experience. They come in a pair, which allows you to simulate all types of massage. Use plain or for cold massage. You can fill the four little cups at each corner with water and put them in the freezer like ice cube trays; when frozen they give a fantastic cold massage. Set of 2.

(To use simply cradle the nukkles in the palm of your hand and slide the four nubs of each one across the back of the person you are massaging. It looks like your fingers should go in the four pockets but they don't need to in order for this to work and feel wonderful for the recipient!)

Colors vary.
