Aura fiber is made from "Aura Stone," a mineral that emits far-infrared rays. "Aura Stone," a deep-sea volcanic rock, is a notable material used in fields such as heat therapy in medical and nursing care, and in health and beauty fields such as "bedrock baths," due to its remarkable far-infrared power. It took 16 years to develop products using Aura Stone as fiber. This is how "Aura Fiber" was born. It is made by kneading Aura Stone into fiber as an ultra-fine powder using a special technique. Simply by applying it to your skin, you will feel a gentle, natural warmth. Aura fiber products warm you comfortably using the heat your body possesses, not from steam or electricity emitted by your body, thus achieving both warmth and health simultaneously.
