"Soak up the sun with black silica." Black silica is said to be the result of diatoms deposited on the seafloor that have changed over hundreds of millions of years, and contains a very large amount of minerals and carbon. It is the only natural ore in Japan that is produced only in Kaminokuni Town, Hokkaido, and absorbs and stores solar energy and emits far-infrared rays with a wavelength of 4~14 μm, which is said to be indispensable for the metabolism, growth, and growth of animals and plants, at a high level at room temperature. The Promo Thermo Mat is a health mat that takes full advantage of the properties of this black silica. Just like a hinatabo, it prevents cold with a pleasant warmth and supports the health of people and pets. If you feel that you may not be feeling well, prevent the cold and support your energy. It is said that various diseases, poor physical condition, and aging are caused by a decrease in immunity and a decrease in metabolism due to cold and poor blood circulation. The Promo Thermomat stores body heat and solar energy, and the far-infrared rays emitted by black silica help people and pets to be energized.
