Thank you for viewing. Yotsuya Otsuka Yoshu Series 4th Grade Science, Volumes 1 & 2 With Answer Key There is some wear and tear from use, such as folded page corners, as the books were used by a child. There is no name written in the books, but there were a few pages with pencil markings, which have been erased. There are no issues with using the books. Please consider this item as a used product.
