Exercise Pillow Use it under your neck to create an arch in your neck. Lie on your back and place it under your calves to reduce swelling. Place it under your spine to correct rounded shoulders and a hunched back. Use it in your pelvis for pelvic alignment exercises. There are many ways to use it! It's not too hard and not too soft, so it won't hurt. Highly recommended for people with stiff necks, hunched backs, and those who want to improve rounded shoulders! I'm sorry, but I'm not considering a price reduction. I will try to ship as soon as possible. Thank you. Regular price: 13,500 yen Cute design, limited edition.
