The Ellipse tools are crafted through CNC machining to ensure each tool provides the greatest feedback and sensitivity when breaking through fascial adhesions. SANITARY: If you are a clinician, please dont use material that absorbs oils and liquids. Thats just gross. Polished steel will not absorb oils and liquids unlike tools made from stone, jade and bone. The Ellipse tools dont have any crevices for lotions and oils to get trapped in either.
