【Sauna Mat Coaster】 This is a coaster from saunizm! I bought it at a sauna event in Tokyo and used it a few times, then displayed it. I think it's hard to get! Quoted from the online store (currently sold out) below: ↓ Sauna mat coaster made with the fabric of the high-quality sauna mat "IOMIX". We wanted you to feel closer to the sauna in your daily life, even outside of sauna activities! We made it with that thought in mind. Use it at home or at the office. A completely original sauna mat coaster that you can't get anywhere else. Each one is handmade with care. Size: 11cm x 11cm What is IOMIX? It incorporates the photocatalytic disinfectant fiber "Ginsekai®", which suppresses the growth of bacteria on the fibers and exhibits a disinfecting function. ※ "Ginsekai®" is a disinfecting fiber that holds silver ions in acrylic fibers, and has excellent disinfecting power, safety, and durability. It is not silver attached to the surface, but rather the Ginsekai® thread, which has silver additives ionically bonded, is sewn in, so the disinfecting function lasts no matter how many times it is washed.
