This is a amphibious mesh hat. You can tie both sides at the Usako-chan part to make it a ten-gallon hat. It comes with a detachable sunshade, so it was very useful during the season when UV rays were a concern. It was only used a few times in one season, so I believe the condition is clean, but there is a name written on the tag, so I have cut off a part of it. It will be shipped folded small. - Size: 48 cm - Adjustment function: String with adjuster Thank you for looking.
