I think there's a lot of content that will interest children, such as science and everyday life, all in color. (My child enjoyed reading them.) Some stickers and supplements may have been used, and there may be writing or some stains. I don't think it will affect reading, but please understand that these are used books. #ShinkenZemi #Benesse #Challenge #1stGrade #2ndGrade #HatenaHakkenBook #3rdGrade #4thGrade #WakuwakuHakkenBook
