I'm selling these items because I found them while organizing unwanted items at my parents' house. This is a set of 6 books by the author Masaharu Taniguchi. ☑️ New Edition: 365 Chapters to Fulfill Your Hopes These books have been stored at home for a long time, so there are stains and scratches. There are also markings and writing inside, but they do not interfere with reading. Please consider purchasing only if you are not concerned about these issues. Thank you for looking.
