This is a REYN SPOONER hat purchased from Shipskids. Size: M Approximate measurement (measured by hand): 52cm. I believe this size is suitable for children aged 2 to 6 years old. I only used it a few times and kept it stored at home because it felt wasteful. I think it can be stylishly worn by both boys and girls. I'm selling it because my child has outgrown it. There are no noticeable stains, but it is a used item, so please understand this before purchasing.
