This is a Will One spoon! It has been stored at home without being used! The "Will One" series conforms to various hand conditions. The "Will" series, the world's first to use a shape-memory polymer that softens with hot water for the handle, changes shape with temperature. It becomes soft when warmed in hot water and hardens when cooled in water (*1). The "Will" series is cutlery that allows you to freely shape the handle by utilizing the properties of this material. It is a long-selling series within the Will Assist brand, which supports people with disabilities to "eat by themselves."
