【Brand New】 HAHONICO Pro Tourmaline Roller Guasha Stimulates acupressure points, meridians, and lymph nodes to relieve scalp stiffness. Promoting meridian flow helps to balance the body's internal systems, leading to beauty benefits. The main body uses elastomer resin, allowing for safe use on sensitive skin. By incorporating tourmaline into the main body, negative ions are generated, and far-infrared effects can also be expected. Price is not negotiable. Thank you.
