I am selling these books because I passed the certification exam. There is a sense of use, but I don't think there are any writings inside. Red sheet included. The book cover has been repaired with cellophane tape. Please check the photos. I would like to sell to those who understand that these are used items. *Instant purchase is welcome. I will prioritize those who purchase immediately, even if negotiations are in progress. "Joho Shori Kyokasho Derutoko Dake!
