This is the Science Manga Survival Series. A set of 22 books. Original price: 1200 yen + tax I am not considering selling individual books at this time. I have graded the condition into three levels, A, B, and C, based on my judgment, with A being the best. Even the A-rated books are not in the same condition as new books displayed in stores. These books have been handled by children and show signs of use. I have included several photos of the books with the most noticeable wear. Some books were used without their covers, so the main body of the book may show more wear than the cover. I will package the books in a cardboard box with rain protection for shipping. 6.
