Elementary Science for the Future, Kyoiku Shuppan 4th Grade, 5th Grade, 6th Grade, Set of 3 Books In excellent condition, having been read only once or so, but there is a small stain on the back cover of the 4th grade book. These are textbooks from the year before last. They will be shipped in a shipping plastic bag via anonymous Yu-Packet Post.
