This is an outerwear item from MUJI. It's reversible, with a cotton check pattern on one side and a beige polyester material on the other. It's also warm, as it has padding inside. The size is 90. There are no noticeable stains or marks, but please understand that this is a used item. ☆ I am also selling other kids' clothes. I offer a discount for combined purchases, so please take a look if you'd like.
