Esker Body Plane New and unused body plane from Esker. Colloidal sterling silver scraping edge and premium teak wood grip base. Get the smoothest skin of your life with the Body Plane – a patent-pending, in-house-designed body exfoliator tool. The Body Plane uses a colloidal sterling silver blunt edge to gently scrape the skin of dead skin, dullness, and impurities while providing an intimate and gentle self-massage. Inspired by the rituals of Greek and Roman bathhouses, the Body Plane is intended to be used when the skin is warm, damp, and freshly anointed with oil.
