This is an 8-book set from the "Detective Conan" Japanese History Detective Series. I used these books at the beginning of my history studies for junior high school entrance exams. The covers show some wear, but the contents are clean with no writing or stains. This is not a complete set. Individual sales are not possible. 1 Jomon Period 2 Yayoi Period 3 Asuka Period 4 Nara Period 6 Kamakura Period 8 Sengoku Period 12 Showa Period Extra Edition: National Treasure Edition
