Thank you for your interest in the product. This is a Doki Doki Literature Club cap. The size can be adjusted with the adjuster. A friend in America gave it to me, but it was a bit too much for me, so I decided not to wear it. It's a used item, so there are some scratches and stains on the inner tag. Please check the photos. Since this is merchandise from before online shops were well-stocked, it's unlikely to be found in Japan. This is a used item, so please refrain from purchasing if you are concerned.
