This is an ehka sopo casquette. The size is listed as free. It can be adjusted with a Velcro adjuster, up to a maximum of about 59cm. Although it is unused, it has been stored at home, so please understand that the condition may differ from completely unused. To keep the price down, I will fold it as lightly as possible and ship it in a shipping plastic bag so that it can be sent via Yu-Packet Post. Wrinkles may occur due to folding, so please purchase if you understand this. The color may differ slightly from the actual product due to the lighting in the photos. Thank you for looking. I have other items for sale, so please take a look if you'd like. #HatGrab Color...Beige系 (Beige-based) Stains, tears, odors, etc....None
