Also, none of them have covers. As shown in the photos, some have damage to the corners of the covers, and some have slight dirt on the covers and spines. Please refer to the photos and only purchase if you are not concerned about these issues. If you have any questions, please feel free to comment. If there are no issues, you are welcome to purchase immediately without commenting. Thank you.
