The first volume has a lot of wear and tear on the cover, but there are no problems with using it. Also, there is writing in the part shown in the third photo, but there is no other writing in either the first or second volume. Although it is for junior and senior high school integrated programs, the content can be used regardless of whether or not you are in such a program. The corresponding sections for the first volume are Lesson 1 to Lesson 7 of NEW CROWN 2, which covers the second year of junior high school English. The corresponding sections for the second volume are Lesson 7 onwards of NEW CROWN 2 (second year of junior high school) and all sections of NEW CROWN 3 (third year of junior high school). This is listed at the lowest price, so I cannot offer a discount. I also sell memorization books, so if you purchase them as a set, I will offer a discount.
