I bought these at Nishimatsuya last summer and wore them a few times. I'm selling them because my child has outgrown them. There are no noticeable stains, but there is a small stain on the back of the blue swimsuit, although it's not very noticeable. The checkered swimsuit is a separate type. The pink cherry-patterned swimsuit has attached shorts. I used them about 5 or 6 times. There's no name written on them, so I think they'll be great for lots of water play this upcoming season (*^^*)
