Two sets of Japanese language workbooks for second graders: * KUMON: Become Much Stronger in Words and Grammar * Z-Kai: Grade Up Problem Collection: Japanese Language Both were used by copying the pages, so there are no writings in the books. However, all pages have been worked on, and there are creases from when the pages were opened for copying. Please understand that these are not new and unused items, and purchase them with the understanding that they are used.
