I believe this is from the early days of Nine Microphones. I purchased it at the Subciety Shibuya store. My husband didn't think it suited him because it sat shallow on his head, so he didn't wear it much and it was stored at home for a long time. It's about 12cm from the crown. The brim is also short. It was about 5cm at the center. Please check the photos for both measurements. The material is wool, polyester, etc. It can be adjusted at the back. There are no noticeable stains, but since it has been worn, please refrain from purchasing if you are sensitive to used items. Please understand that this is a used item before purchasing.
