Provides an avenue of release for pent up stress & tension. Measures approximately 2"W x 1.5"D x 5.5"H (at widest points). Great physical therapy for arthritis and other nerve/muscle conditions. Use at the office, home, school, gym, anywhere. Easy to grip and squeeze when needed for stress relief or therapeutic maneuvers. Stress can occur anytime and anywhere. It helps to have something handy to squeeze your hand around to help vent the pressure and relieve that feeling that stress can bring on. They're soft enough to be comfortable and hard enough to be beneficial. Using these stress toys can help people with arthritis and certain muscular conditions, too.
