This is a children's outerwear item from MUJI. The outside is boa fleece and the inside is fleece, making it warm. I am selling it because my child has outgrown it. Although it hasn't been worn frequently, please refrain from purchasing if you are concerned about minor details, as it has been worn by a child. I have stamped the tag with my child's name, so I will cover it with a plain sticker before shipping.
