Upgrade your Wellbox device with the Wellbox Roll Head 1. This is the smallest roll treatment head in the collection, offering you targeted treatments on those hard to reach areas. When connected to the device, the rollers gently mobilise, sculpt and relax your muscles to improve your skin's health. With regular use, you'll notice reduced muscular tension, as well as firmer and softer skin. The compact design makes this perfect to use across the hands, knees, ankles and arch of the foot.
