This is a clear file from the April 2010 issue of Animedia magazine. (Not for sale) A4 size. It is a new, unused item, but please refrain from purchasing if you are sensitive to items that have been stored at home for a long time. There are no noticeable stains. - Work: K-ON! - Size: A4 size It is from that time, so I believe it is rare. Thank you for looking.
