This easy to use glove features an adjustable strap that fits over almost any hand – left or right. Featuring 9 metallic balls evenly distributed over the glove for the best coverage each ball is able to roll 360 degrees which means you can move your hand in any direction over the skin. No lubrication is needed for best results. The glove is made from flexible TPE. The reverse side that goes against the palm has hundreds of little nubs to make wearing it comfortable as well.
