You can sit in your favorite position, such as with your legs extended, cross-legged, or kneeling. Opening and closing your legs, as if squeezing the protrusions at the front, stimulates the inner thigh muscles, helping to tighten the thighs, exercise for a beautiful abdomen, and achieve a toned waist, beautiful legs, and pelvic correction. I bought it new but never used it, so it has been stored away... It has been stored at home. Please refrain from purchasing if you are concerned about minor details or are overly sensitive. I have set the price to the lowest possible, so it will be packaged with simple bubble wrap. If you prefer cardboard packaging, please purchase a cardboard box.
