This is a denim pen case featuring Pom Pom Purin. (Some images have been processed to prevent reflections.) I put some items in it for a short while, but I took them out immediately and stored it. I don't see any noticeable stains, but there's a possibility I missed something. It's a very cute item. It's an old item, so it's for those who don't mind the details. There may be a slight old smell due to aging. Please consider carefully and purchase after you are satisfied. Thank you for your understanding.
