Thank you for viewing. This is a complete set of NANA volumes 1-21. Volumes 2, 15, and 21 do not have obi, while the rest do. However, the obi on volume 18 is partially torn. Also, volumes 13-21 are first editions. *While I believe they are in good condition as they were stored on a bookshelf, please consider that they are used. *Returns and cancellations are not accepted after purchase.
