Acupuncture has been used for centuries to rid the body of stress and pain. Now you can enjoy these benefits at home, without the needles. Simply slide the tip of the pen over the skin using gentle pressure. When an acupuncture point is located it beeps and emits a safe, low-intensity electrical pulse that feels like a tingle-like sensation. Includes instruction booklet with acupuncture point chart. Requires 2 button cell batteries (included FREE).
