I bought it at Universal Studios Japan about 15 years ago. I only tried it on and kept it in my closet. There are no noticeable stains or scratches, but there are some folding wrinkles.
Please refrain from purchasing if you are nervous as it will be stored at home for a long time.
It's a button on the side.
It has fur on it and is very cute.
The size is 57 cm.
I don't think you can get it anywhere else
This is a rare hat.
