"Top Class Problem Collection: Arithmetic, Grade 2" Bunri Editorial Department Price: ¥1,300 + tax There are a few places where diagrams and clock faces were written on with pencil, which have been erased. I have checked, but there may be oversights. Please refrain from purchasing if you are concerned. The answers and check-up tests can be separated from the main problem book and managed as separate booklets, and they have been separated. The check-up tests are unused and have not been separated from the answer booklet. There is a slight fold at the top of the spine of the cover, but the contents do not show much use."
