The TriggerPoint Handheld Massage Ball allows you to glide a wide, rounded pressure point along sore muscles and joints for the ultimate on-the-go massage experience. Gone are the days of uncontrolled friction or messy massage oils. This handheld massage ball is as easy to use as applying pressure and gliding the ball. You can now quickly massage larger surface areas or concentrate on sore points longer. Looking for a bit more friction in your massage? Press the rubber button on the other side of the roller to stop the ball from moving.
