Thank you for viewing. I purchased this in January of this year and used it after making copies, so I think it's clean. However, my child may have used it without my knowledge, so I checked for writing, but I couldn't find any. (I apologize if I missed anything due to my amateur inspection.) However, please refrain from purchasing if you are looking for a perfect item, as it is a used item. I do not offer discounts. Also, I do not hold items. Thank you for your understanding.
