Thank you for viewing this item. This is a 100% wool hat made by Ifti Art! The size can be slightly adjusted with the inner band. I fell in love with it at the Okachimachi 2k540 store and purchased it new for 14,300 yen, but I have kept it at home without ever using it. I am selling it now to declutter. I plan to lower the price from time to time depending on the situation, so please refrain from negotiating the price. m(_ _)m
