BELLY BAND, a line of health-promoting goods and apparel that supports improved blood flow, incorporates natural mineral-infused yarn. GIEG's Magic Yarn The magic yarn used in GIEG items is infused with natural minerals such as germanium and zirconium. These minerals release negative ions at temperatures above 32°C, which interact with the bioelectric current of the human body, supporting the normalization of blood flow and lymphatic imbalances. The philosophy is: Recovery → Refresh → Relaxing → Charging. By reducing active oxygen, which is a cause of "feeling sluggish" and "getting tired easily," and increasing oxygenated hemoglobin, oxygen can be distributed throughout the body, leading to the four effects mentioned above. *Please avoid tumble drying.
