Hama Gakuen - Grade 5 Math: Highest Level Special Training First and Second Courses, First Volume to Fourth Volume Problem Sets and Answers, Complete Set (all 16 books) These are materials used in the 2024 academic year. Thank you for viewing. I have checked and erased any writing. (I apologize if there are any oversights. Please understand that eraser residue may remain.) Also, some books have had names written on them or have had name stickers removed, and there is overall wear and tear. Some pages have folds. I believe they are usable without any problems, so please consider these points before purchasing. Shipping and handling fees apply. I do not offer discounts. I want to sell the entire set, so I am not selling individual books. I also do not offer holds. Thank you for your understanding.
