【Brand New】 HAHONICO Pro Tourmaline Roller Gua Sha Stimulates acupressure points, meridians, and lymph nodes to relieve scalp stiffness. Promoting meridian flow helps to balance the body and can be expected to have beauty benefits. The main body uses elastomer resin, so it can be used safely on sensitive skin. By incorporating tourmaline into the main body, it generates negative ions and can also be expected to have far-infrared effects. Price is not negotiable. Thank you.
