This is a truss for hernias from a company called Truss Care Japan. A special spring is built into the belt, and the elasticity and restoring force of the spring prevent hernias. It is made of highly waterproof material, so it can be wiped with water or alcohol. (It cannot be washed with water.) Unlike supporters, rubber types, and Morita steel types, it has a buckle adjustment, making size adjustments easy. Durable materials are used, and the parts can be replaced, allowing for long-term use. All items are new and unused. Includes instructions. Made in Japan. Sizes: M size (waist 80cm-92cm) L size (waist 92cm-102cm) Available for left side, right side, and both sides. *When ordering, please specify the size and side. Mercari sales history (as of October 2025): 12 units for one side
