Used after the birth of my two children. I didn't use it much, so I used it about 10 times. There are small pills from washing and use, but there are no major stains, tears, or fraying of the zipper tape, and it can still be used. It has a ribbon, so it's easy to tell the front and back. I've included a screenshot from the official website for reference, but the closure is reversed from the one in the photo. I bought it 7 years ago, so the production period is different. I believe the effect is the same. I bought it for about 4000 yen. Black polyester maternity belt, size M-L. - Size: M-L - Color: Black - Material: Polyester - Brand: Dylon Thank you for looking.
