This is a complete set of Oshi no Ko volumes 1-16. All volumes were purchased new from a bookstore. They have been stored at home after being read 1-2 times (some are unread). Compared to volume 16, the earlier volumes show some yellowing, but it's not significant. Please check the condition and consider purchasing. The volumes will be packed in OPP bags in groups of a few, and shipped in a cardboard box.
