Kao MegRhythm Steam Thermo Patch Stick On Garment Fragrance Free is a self-heating thermal patch designed to gently warm the belly and waist area for long-lasting comfort. The patch adheres to the inside of clothing or thermal undergarments and releases soft, steam-infused heat that penetrates deeply, helping the body feel relaxed and at ease. It maintains a comfortable temperature of around 40 °C for 5 to 8 hours, providing consistent warmth that is gentle on the skin without making clothing damp. Designed specifically for the female stomach and waist, the thin, discreet patch fits comfortably under clothing and features a soft, textured mesh that is kind to delicate skin. Regular use may help ease muscle discomfort, support circulation, and promote digestive comfort, making it ideal for daily wear, cold days, or moments of physical tension.
