Free size (Please consider this as a guideline as it's measured by a layman) Flat measurement: Head circumference: Approximately 42cm Height (folded): Approximately 22cm Purchased almost 10 years ago, no brand but made in Japan. It has been worn frequently and shows overall signs of use. There is also some overall fuzzing. It also feels like it has stretched slightly compared to when it was new. There are no noticeable scratches or stains, but this is based on a layman's observation and is a used item. There is a possibility that I may have overlooked small holes or scratches during inspection that I, as the user, am not aware of. Please refrain from purchasing if you are concerned about small details, seek perfection, or are overly sensitive. I don't live my life centered around Mercari, so it takes an average of 2-3 days to ship. Please comment before purchasing if you are in a hurry. (This may vary depending on the situation and whether I can accommodate your request) Also, I have one dog at home, and I will try to remove any hair before shipping, but please refrain from purchasing if you have allergies or are sensitive to this.
