| The ultimate stress busting massage tool for the twenty-first century. Crafted of space-age polymer, the 3.9" x 3.9" x 3.9" pyramid-like design allows you to apply relaxing, pain releasing pressure to the back, neck, shoulders, and muscles throughout the body. One, two, or three knobs may be used at the same time. The smaller knobs will give a deeper pressure, the larger knobs will give a more diffused, gentler pressure. |
