I'm selling this item at a low price because I used it after giving birth and it shows signs of wear. There are some areas where it's become misshapen. Please understand the condition before purchasing. I don't think there are any dark stains, but there are some faint stains and damage like pilling. This is a size L pelvic belt made of nylon and polyurethane. - Brand: Toko-chan - Size: L - Material: 100% nylon, 100% polyurethane Thank you for looking.
