Two Chomei Stones Authentic product purchased from a retailer To use, place them in the bathtub during bathing. You can use the Chomei stones alone, but some people place them on a small slatted board or wooden plank. They are also recommended for foot baths. Once the water is warm, it's recommended to place your feet on the stones and soak for a long time, just like in a regular bath. A friend's family purchased these for the recovery of a family member's illness, and they bought two sets to try them out as well. Although not used daily, this person used them for 5-6 months. This person is a clean freak and polished the stones frequently, so some parts of the sticker have peeled off. I checked, and there were no chips, cracks, or fissures. They were given to a family member for illness recovery, and the family member successfully recovered and is now living a normal life. It seems that the friend's family had promised to go on a hot spring trip together after the illness was cured, and they decided to give away the Chomei stones to help pay for the trip. When the friend and their spouse tried them, they said that the first bath (the first bath after cleaning) made the water feel softer even without bath additives, and the wife's cold sensitivity improved, and the husband's high blood pressure and menopausal symptoms improved. The family member recovered from their illness, but they can't live without them anymore because of the improved immunity and recovery from illness. As a side note, wealthy people seem to use them in the water for their koi fish. Some people have been using them for about 20 years, and they seem to last semi-permanently. I have the items in my possession, but I'm not an expert, so I will contact the owner. Please understand that responses to questions may be delayed.
