New, unused. You can easily massage the pressure points in your lower back, back, and buttocks while lying down. To use, place the "Pelvic Artisan" on the floor, align the spheres (acupressure balls) with the area you want to target, and simply lie on top of it. Your body weight will apply pressure to the spheres (acupressure balls), providing the effects of "anma" and "shiatsu" massage. Focus on your buttocks, lower back, and back, using it for 4-5 minutes per area, for a total of 10-15 minutes a day.
