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 versatility, CONTOUR M is great for application across the whole body. Use with the dome side face down to create broad strokes across large areas of the body. You can also face the four small nodes down for targeted, multipoint stimulation of the muscles. The versatile shape offers limitless possibilities.
