I've used these a few times since purchasing them, and they're relatively clean. They have the same design as the adult version, so you can match with your child. Also, they have a side zipper, so they're easy for children to put on, even though they're high-cut. They are currently sold new for ¥4730. I've lowered the shipping cost as much as possible and reflected it in the price. They will be shipped via Yu-Packet Post.
