Nichinoken 5th Grade 2023 Spring Seminar Applied Textbook I purchased this at the cram school when my child was attending Nichinoken. There is almost no writing in it, but there are a few pages with lines drawn in red ballpoint pen, as shown in the photos. As shown in the photos, the name on the back cover has been blacked out with a marker. I would appreciate it if those who understand that this item was used by a child and has been stored at home would purchase it. Also, as returns are difficult for items that can be copied, please confirm the condition carefully before purchasing. We do not have any pets or smokers.
