Proprietary brand “Only One®” products.

Our Only One® “hot water bags”, “water pillows”, and “circular mats” are manufactured at the Naniwa Rubber domestic plant. As a company providing medical-use rubber and medical equipment, we ensure quality by remaining dedicated to domestic production. By using both synthetic and natural rubber, we promote environmentally-friendly practices while ensuring abrasion resistance. Now offering highly applicable general silicon products, today our products are used not only in hospitals and medical facilities, but also in many households.
