Thank you for viewing. Demon Slayer manga, volumes 1-23 complete + side story, with enclosed flyers. Volumes 1-17 were purchased together, and volumes 18-23 are first editions. Volumes 17 and 20 are missing their obi (paper bands). Volumes 18, 20, 21, and 23 have the enclosed flyers. They have been stored away from sunlight, so there is no yellowing or staining. There are no noticeable stains, but as I am an amateur, there may be oversights. Please inquire if you have any questions. Thank you very much.
