Develi 1973 Double-Sided Hard-Medium Hard Bath Bath Scrub The new design of the Develi scrub brand is a double-sided Bath and Bath scrub. With its striped Hard Surface, it removes dead skin and dirt from the body in application. With its Medium Hard Surface, it helps your skin have a flawless appearance. Depending on your bathroom habits, it is recommended that you start the application with a hard surface, then massage your skin with a medium hard surface without applying too much pressure and force. As a result of contact with water, the product reacts as a tree sees water, causing the product to harden and have a swollen texture. Close weaving technique. Tree bark thread essence.
