“Hot Spring Healing Blanket” uses the power of natural radium ore to provide gentle, onsen-like warmth simply by wearing it. Designed for women who lack time for self-care and experience fatigue or poor sleep, it offers instant warmth, easy machine washing, and a reversible, year-round design. Developed through repeated prototyping and feedback from female advisors, it achieves a texture that helps both body and mind relax. Crafted with care, the blanket supports busy mothers and working women, making everyday life a little more comfortable and restful.
