This is a popular item and currently difficult to obtain. It's convenient for use when your hair has fallen out due to medication or treatment, or for everyday outings and fashion, as it doesn't get stuffy. Unisex. The second photo is a sample of the same color hat without taking the contents out, so it is new and unopened. I bought extra because I liked it and it's easy to wear, but I have some left over, so I'm selling them. Retail price is 3850 yen.
