This is a set of four books, as shown in the photo. If you have any requests, such as swapping with other books I have listed (see the last photo of this listing), please let me know in the comments. Generally, there are no noticeable stains or damage (therefore, I've marked the condition as "no significant scratches or stains"), but if you'd like to check the condition of the books in detail, please contact me, and I will add more detailed photos. I am also listing these on other sites, so the first person to purchase will be given priority.
