Used about 3 times. It's completely waterproof, and I took it to the snowy mountains (just playing with my kids), which gave me peace of mind. Other than that, it's been stored in the closet. There's one spot that's dirty (last image), but I personally think it's quite clean. I don't think there are any other stains, but please understand that this is a used item before purchasing. I've only wiped it with water. ※Due to family circumstances, I often can't ship items immediately. If you're in a hurry, please be sure to check with me in the comments.
