HAHONICO Pro Tourmaline Roller Kassa Stimulates acupressure points, meridians, and lymph nodes to relieve scalp stiffness. Promoting the flow of meridians helps to balance the body and can be expected to have beauty benefits. The main body uses elastomer resin, so it can be used with peace of mind even on sensitive skin. By incorporating tourmaline into the main body, it generates negative ions and can also be expected to have far-infrared effects. Will be disinfected and shipped. Thank you.
