Purchased in October 2025. It comes with both a cool-touch cover and a regular cover, so you can try them depending on the baby's reaction. The covers alone cost 4000 yen, so I think it's a great deal. I didn't use it much, so there were no incidents that caused it to get dirty. There are no stains on the main unit or the covers. I don't see any stains or dirt with the naked eye, but please understand that this is a used item. It will be shipped in a plastic bag and then in a cardboard box.
