This is our popular silk belly band. This listing is for two. Please choose your preferred colors. We don't have much stock this time, so please order soon. These are slightly imperfect, made in Japan by a long-established underwear shop. They are almost indistinguishable from first-quality items. In stores, they typically retail for around 2000 yen each. The part that touches the skin is 100% silk, and the outer layer is cotton. They also contain polyurethane for stretch. Suitable for those with sensitive skin. Despite being silk, they are thin and warm, and won't show under your outerwear. Measurements (laid flat): Length 30cm, Width 25cm. Comfortable to wear while sleeping.
