・ US Navy flight cap from the 1940s. Also known as a Blue cap. Made of sturdy wool from the WWⅡ era, it's a ✨work of art✨. ・ Size is 52cm, not a large size, so Rather than wearing it yourself, It's recommended for collectors, especially those who collect US Navy items. ・ Non-smoker, no pets. ・ Anonymous shipping via Rakuraku Mercari. ✨I also have other military items listed.
