This is a set of volumes 1-21 of "NANA." As shown in the images, there is some aging and some yellowing, but as you can see in the images, there is no problem with reading them. I am selling these because I am decluttering due to a move. Due to the aging, please check the images and consider purchasing only if you understand. P.S.: I forgot to take a picture of volume 18 when taking pictures of all the volumes, so the image is separate, but as shown in the last image, it is included in the package. - Volumes: 1-21 - Title: NANA - Genre: Shoujo Manga Thank you for looking.
