Used a few times. Home cleaned. All Invel products incorporate finely crushed bioceramic (MIG3). This is a special technology developed by Invel, and MiG3 is characterized by its powerful emission of far-infrared rays (especially nurturing rays). Nurturing rays have the same wavelength as the human body and are characterized by their high deep-penetrating power to transmit heat. By resonating with water molecules in the body, they provide a warming effect and balance the body, leading to a healthy state. This is the bioceramic power of Invel products.
