This is a waist nipper for use from 6 weeks to 6 months postpartum. It allows for easy size adjustment and has six bones for firm compression. I received it from a friend, but I didn't use it, so I'm selling it. It's unused, but the Velcro part is slightly dirty due to poor storage, so I will wash it before shipping. I will be selling it without the case shown in the photos. - Brand: Osaki - Model Name: Waist Nipper - Size: M - Material: 80% Polyester, 20% Polyurethane - Usage Period: Approximately 6 months - Design: With lace - Features: Body-fitting design
