Using the penetrating power of nano far infrared light waves, the energy substances that help the human body get rid of diseases are brought to the deep layer of the body. Its principle of action is similar to that of the hundred-year-old light moxibustion instrument, and it is invisible light, but the energy substance is slightly different from that of the hundred-year-old light moxibustion instrument. The mode of action is mainly thermal energy, supplemented by far infrared light waves. This product is completely different from the so-called "far infrared" objects on the market. We use military raw materials, and its function is hundreds of times that of ordinary "far infrared" objects.
