I tried it about 4.5 times, but my child didn't like it, so I'm selling it. It's a shame since I just bought it, so I hope someone will use it. It's clean as it was used for a week. There is some dirt on the Velcro part (see image 5). It can be used without any problems, and the rest is clean. No box, will be folded and shipped. - Product Name: Baby Rolling Prevention Belt Sheet - Price: ¥3,980 - Design: Bear pattern - Supervised by: Pediatrician - Size variations: 2 sizes available - Purpose: Prevents babies from rolling over
