Nichinoken (N-noken) 6th Grade 2025 Academic Year Spring Seminar Special Course Skill Up Applied 4-Subject Set Calculations written in pencil have been carefully erased. There are no issues with usage, but faint marks may remain. I have reviewed the materials 3-4 times to ensure nothing was missed. I believe they are in good condition. Includes answer key and explanations. Returns are not accepted as this is a copyable product. These are used items that my child has used. We hope they can be helpful to those who understand and are interested in using N-noken materials. Thank you very much.
