I bought this to wear when taking my child to and from kindergarten. The zipper works fine, and the size is probably around 110-120. There's a stain-like mark on the back, at chest level, that didn't come out. I don't have any pets, and I don't smoke. It was stored at home, but please only purchase if you understand that it's a used item. *I'm also selling other children's apparel. If you purchase multiple items, I'll discount the total by 200 yen.
