The Uniqlo pants on the left are size 70, which is a bit large. The others are size 80. They were worn for one season at nursery school. The tags are faded and unreadable. I don't see any noticeable stains, but they show signs of wear. There may be some overlooked imperfections, so please refrain from purchasing if you are concerned about minor details. These are suitable for those looking for clothes to wear at nursery school that can get dirty, or those who understand that these are used items. Thank you for your purchase.
