Purchased at Rintosull (Pilates studio). Corrects the pelvis, etc. to the correct position and enhances the exercise effect. Retail price: ¥14,000 Brand new, unused I'm selling one because I bought two and don't need both. This is a rare L size. Recommended for those over 160cm tall, as M might be too tight.
