No plans to sell individually. Please refer to the images for any writing or stains. If you would like more details, please leave a comment and I will respond. Basically, for books with writing, I've included the most written-on part of each book. For books without individual images, I couldn't fully confirm, but I didn't see any writing. Please forgive any overlooked writing. Please refrain from purchasing if you are overly concerned about condition. The books will be disinfected with alcohol before shipping. Thank you for your understanding.
