This is a history manga for elementary school students, and it's easy to understand. I'm selling a manga my child was reading. It's an old book, so there are small stains on the edges and top, but there's no problem with reading it. Tape is used to prevent the cover from being removed. If you are concerned, please refrain from purchasing. - Series Name: Study Stadium - Volumes: Volume 1, Volume 2, Volume 3 - Target Age: Elementary school students - Content: History study - Features: Rich in illustrations and easy to learn Thank you for looking.
