The Light-Life® Acupressure Tool, gold plated is 6 " in length and made from copper, gold plated. The energy flows in both directions in the tool. It balances the acupressure points. The loop seems to concentrate life force energy, use for 2-5 seconds on skin. The ball seems to create the flow/reactivation of life force energy. According to Slim Spurling's best estimate, by placing the Acupressure Tool on the acupressure points, the proper frequencies are re-introduced to the system, amplified by the tool, thus re-establishing the proper frequencies and deleting incorrect ones.
