I purchased Grand Blue new around 2018. I purchased the complete set of BakaTest new around 2019. Volumes 9, 10, and 11 of Grand Blue have some sun damage, but there's no problem with reading them. Volumes 11, 12, and 12.5 of BakaTest are slightly bent, but there's no problem with reading them. The condition is generally good, except for some parts. They are works by the same author. I've read Grand Blue about twice. I've read BakaTest about once. I am selling them because I have switched to e-books. No individual sales. Instant purchase is welcome. If you have any other questions, please feel free to ask.
