This is a pelvic belt that can be used before and after childbirth. The size is M. I haven't used it very often, but I bought it about 3 years ago and have been storing it at home. To simplify packaging, I plan to discard the box. If you absolutely need the box included, please comment when you purchase. Shipping costs will be higher, so I will include it if it's okay to flatten it. I do not have any pets or smoke.
