This is an English textbook used at Tetsu-juku in the 2021 academic year. It follows a weekly theme format, making it ideal for those who want to learn grammar at a set pace. There are no markings inside the book, but there are small creases and scratches on the cover and top from being carried around. (As shown in the photos.) As you can see in the third photo, there is no name written, but there is a trace of where it was erased.
