"Kotoba Navi, Volume 1 & 2" 1. Volume 1: 2nd Edition, 7th Printing, November 15, 2021 2. Volume 2: 4th Edition, 3rd Printing, June 26, 2023 Planning & Production: Savix Elementary School Division ★ I purchased this new and read it once. There is a check mark on page 4 of Volume 2 (see photos 3 & 4). Also, there are scuff marks on the corners as the books were kept in a bag (see photo 5). Note that there are no check marks in Volume 1. There is no writing in either book. There is no name written in either book. ★ In my opinion, I think these books can still be used sufficiently.
