Kanji Kentei (Japanese Kanji Aptitude Test) Level 4 & 5 Japan Kanji Aptitude Testing Foundation Level 5: The spine has some slight discoloration. Level 4: There were a few places where pencil marks were made on the numbers in the questions, so I erased them. (See photo 5) There is no writing in the books. I think the books are in good condition. In addition, there may be oversights, but please understand.
