This is a simple cap made of nylon material. The color is difficult to tell, but it's navy. It can be adjusted at the back as shown in the photo. I remember buying it at Three Coins, but I don't think it was 300 yen. It will be folded up small and shipped via Yu Packet Post Mini. How about it for the upcoming leisure season? - Color: Navy - Material: 100% Nylon - Size: Free Size Thank you for looking.
