I purchased this new at the maternity clinic and used it for two weeks before delivery and one month after. I used it before delivery under the guidance of the clinic, and it gave me a sense of security when walking during my final month of pregnancy. By the way, I had an easy delivery. There is some pilling, but the Velcro is clean and still fastens securely, so it can be used without any problems. For those who understand that this is a used item, thank you. This L-size maternity belt, made of nylon and cotton, provides comfortable support. - Brand: Aoba - Size: L - Type: Maternity belt
