I opened and checked the contents of only the second photo, and there is a crease in one part, but it's in good condition. The other four books are new and unopened. My mother bought them for studying for 2800 yen, but I am selling them because they were for Chinese speakers. Although they were for Chinese speakers, they also have furigana in English and Korean, so I think people other than Chinese speakers can also use them. Instant purchase is OK.
