The Jimmyjane Contour M ceramic massage stone has been a wonderful addition to my growing collection of massage products. It's easily warmed and holds onto the heat well, resulting in deep, relaxing massages. The nodes are great for working out the kinks, while the smooth, large surface of the other side is more suitable for soothing, broad strokes. This stone glides easily with just a little bit of massage oil, but can get a little difficult to hold onto, if you're not careful.
