What the landlord said should be far infrared foot bath bucket, also called spectral foot bath bucket, with temperature control, water-free foot bath from foot to knee to leg, full coverage, iron fir material, far infrared carbon plate heating, tourmaline physical therapy, and now the market price is around 750. The far-infrared foot bath bucket I bought has been used all the time, and the effect is very good. It has a very good effect on detoxification, physical therapy, arthritis and old cold legs.
