Safe. Graphene ribbon products work with low voltage current and have good thermal conductivity. Graphene has a honeycomb internal structure, which can balance heating without burning, reduce harmful electromagnetic radiation, and is safe, healthy and worry-free. Graphene waistband aims to provide waist support and protection, relieve waist pain and discomfort, improve waist posture and reduce waist burden by providing appropriate pressure and stability. At the same time, it also exerts the special properties of graphene, such as the release of infrared radiation and far infrared rays, which helps to promote blood circulation and relieve muscle fatigue.
