Retail Price: ¥1280 Color: Black Material: EVA Material Type: Free of latex and phthalates Designed with a three-dimensional structure that makes it easy to naturally focus on the muscles around the pelvis just by sitting on it. The central bulge gently stimulates the pelvic floor muscles (PC muscles). Simply place it on your usual chair or the floor to make your daily "sitting time" a self-care habit. Recommended for those who are concerned about their posture or want to be conscious of their hip line. Can be used during "while-doing" activities such as desk work, housework, and watching TV. Lightweight and compact, making it easy to use at home or in the office! A self-care item that even those who are not good at exercise can start without special knowledge or skills. There are no problems with use, but it is a discounted item due to scratches.
