This is the new curriculum Chart Shiki Basic Mathematics C textbook. Please check the images carefully. It is new and unused, but I wrote my name on the inside of the cover. I have erased it with a marker and covered it with masking tape (see images 2 and 3). There are no markings inside. There is a small scratch on the back cover (see image 3). Please consider purchasing if you understand. Please refrain from purchasing if you are sensitive to imperfections. Thank you for viewing.
