I purchased this from Orihica about two years ago. It has been stored in the closet, unused. The mark in the second photo didn't come off when I tried to brush it, so I think it's a stain that occurred during storage. It's a very small stain. Size: L If you have any questions, please comment before purchasing. Thank you. I will fold it to fit in a post-box size for shipping. Thank you for your understanding.
