Massage Ball Set · pair

A pair of 2.5-inch solid rubber massage balls for the spots a roller cannot reach — under the shoulder blade, the arch of the foot, the glute. Solid rather than hollow, so they stay firm under bodyweight and do not deform against a wall or the floor. The natural-rubber surface grips skin and clothing enough to stay where you put it. Two balls let you work symmetrically or tape them together for the muscles either side of the spine. Firmer than a tennis ball, more precise than a roller, and small enough to keep in a desk drawer or a bag lid. Wipe clean with a damp cloth.
