Add to your daily warm-up routine! How about an "O-Mata Kairo" (Vaginal Warmer)? This is a 23cm size, waterproof, 7-layer cloth napkin with a pocket. Insert a non-adhesive mini-sized disposable warmer into the pocket and wear it. It warms you from the core of your body and feels wonderful! Warming your vaginal area warms the vagina and uterus, and has various effects such as improving cold sensitivity, constipation, menstrual problems, and menopausal symptoms. It's a waterproof type with 4 absorbent layers, so it's also suitable for light incontinence and menstruation! It's thick enough so it doesn't get too hot, and it provides gentle warmth. **To prevent low-temperature burns, please refrain from using it while sleeping, and remove the warmer immediately if you feel it's too hot.** The skin-facing side is made of soft W-gauze in a cafe au lait color that doesn't easily show stains. It's made of safe and secure 100% cotton, made in Japan. Double gauze, woven like two layers of gauze, is characterized by its smooth texture and breathability. It becomes softer and fluffier with each wash. *Please note that double gauze and cafe au lait are not unbleached fabrics. The flannel used for the absorbent cloth is additive-free and unbleached fabric. ■If you wish to change the skin-facing fabric other than double gauze cafe au lait, please leave a comment. ■Product price: 2400 yen + shipping 180 yen = 2580 yen If you purchase 2 or more sets, we will discount the shipping fee and create a dedicated page, so please comment before purchasing.
