Purchased on Rakuten in January 2023. It seems to be selling for 6200 yen on Rakuten. I used it when I wanted to hold my child for a short time when going out. Used for about a year, about 10 times. After that, it was stored at home. There are no noticeable stains or dirt, but there is something like a stain on part of the belt. It's barely noticeable, but please check the photos. Please understand that this is a used item. When shipping, the box may be flattened.
