This hat is made of a material with a wool-like texture, like sheep's wool, and is a slightly stiff fur rather than fluffy♪ I purchased it at a used clothing store, and there were no detailed product tags attached at the time. Therefore, the exact material is unknown. The inside is nylon. There is no wire, so it can be freely shaped by adjusting the angle you wear it at ^_^ Size: Head circumference: Approximately 55cm Brim: Approximately 7.5cm Height: Approximately 9cm #BucketHat #SheepFur #Bakeha (Bucket Hat) #FurHat #FauxFur
