This is a set of three books perfect for studying for the Kanji Kentei (KanKen) Level 7 exam. ① Ichimaru to Hajimeyou! Wakuwaku KanKen (Let's Start with Ichimaru! Exciting KanKen): Purchased new from a bookstore. Has writing in it. See photo 3. ② KanKen Past Exam Questions Level 7: Purchased on Mercari this spring. There is no writing in the questions, but the previous seller's exam number is written on the attached answer sheet. No writing by me. See photo 4. ③ KanKen Kanji Study Step Level 7: Purchased new from a bookstore. No writing. See photo 5. I apologize if I missed anything. I only used these books for three months, from March to May of this year, so I think they are still perfectly usable. I would appreciate it if those who don't mind the writing could use them. Please refrain from purchasing if you are looking for something in new condition. Please understand that these are home-stored, used items, and have been used by children.
