I used this at a special needs school in the high school department. It's easy to understand and helpful. There are no writings or marks. There are some marks from peeling off a label maker sticker that was on the name. Reference books for Japanese and Math that are useful in daily life. No price reductions possible due to shipping and handling fees. - Title: Kurashi ni Yakudatsu Kokugo (Japanese Useful in Daily Life) - Title: Kurashi ni Yakudatsu Sugaku (Math Useful in Daily Life) - Publisher: Toyokan Publishing Co., Ltd. - Author: Kōmyō Ōki Thank you for looking.
