Thank you for looking! (*^^*) Yotsuya Otsuka Pre-Study Series 4th Grade Summer Course Math, Science, Social Studies, Japanese I summarized the content in a notebook without writing in the textbooks. I used sticky notes for the check points, and I removed them all before listing, but please forgive me if I missed any. I have checked it quickly and found no writing, but please forgive me if I missed anything as it is a casual inspection. There may be some scratches, dust, and dirt as it has been stored at home. I think the condition is good for a used item, but please do not have excessive expectations as it is a used item by a child. I don't think there are any major problems that would hinder your studies. I will set the price low, so I will sell it to those who understand that it is a home-stored item and a casual inspection (∗ˊᵕ`∗) I am organizing my belongings, and I am also listing many other items at the same time, so I have not been able to check them in detail. If you have any questions, I will check the parts you are interested in individually, so please feel free to ask if you are considering purchasing (*^_^*) ※ I am also selling many other materials for junior high school entrance exams and home study materials for elementary school students, such as Yotsuya Otsuka and Waseda Academy materials, so please consult with me if you would like to purchase them as a set or individually.
