These versatile leggings feature three main functions: they address women's concerns about their stomachs with a shaping effect, provide hip-up body shaping, and support the skeletal structure and muscles. They also have a patented function that enhances exercise performance, such as leg opening and stretching, and assists knee movement, which is expected to increase exercise power. I've used them a few times, but I'm selling them because I don't have the opportunity to wear them. Please consider purchasing if you understand that there may be some folding wrinkles from being stored at home. They have been washed. Immediate purchase is available. Thank you for looking.
