These shorts were produced by Chika Amsaki, a health and beauty stretch trainer, based on the concept that women can achieve "health," "beauty," and "style improvement" through flexible joints. They feature a wide corrective belt that tightens and supports the muscles around the pelvis. These multi-functional shorts allow you to tighten your abdominal area, support your hip joints, and promote beautiful posture, all in one. Although brand new, the packaging is soiled, so the item will be shipped as is.
