CONTOUR Ceramic Massage Stones offer a modern take on traditional hot stone massage. Made of double-fired porcelain, they're biocompatible, durable and easy to clean. With smooth, polished surfaces, they glide over the skin, relieving tension as they go. Use them individually, or pair the stones for different massage techniques. Warm them up to soothe, or cool them down to refresh. Designed for deep, kneading massage, CONTOUR I provides relief for tired fingers and thumbs, and helps with hard to reach places. The end can be used to focus pressure on a very small area, allowing the deepest stimulation of the muscle. You can also roll the stone lengthwise along the body to apply deep pressure to multiple points in tandem. The versatile shape offers limitless possibilities.
