This hand-held tool comes with a set of 7 glass rods, each infused with natural dyes of different spectral colors (red, orange, yellow, green, turquoise, blue and violet). The rods emit the precise frequencies of colored light deemed by Mandel to be most effective for his therapies. They have a patented “pyramid tip” suitable for focusing the frequency on an acu-point. When light is applied through the pyramid focus, research has shown that, although the light may appear to diffuse slightly on the surface of the skin, it actually collects under the skin into a single focused beam that rapidly penetrates deep into the body. Cost is $560 plus shipping.
