"High Class Test Mathematics, Grade 7" Chugaku Suugaku Mondai Kenkyukai (Middle School Mathematics Problem Research Group) Price: ¥900 It seems like it was used with writing in a separate notebook, but there are some places in the first 10 pages where problem numbers are checked with a red pen or highlighted with a highlighter. There is no feeling of use, and the book itself is in a clean condition. I apologize if there are any oversights. #ChugakuSuugakuMondaiKenkyukai #Book #Nature/Mathematics
