This is a set of 5 books from the Kadokawa Manga Science Series "Which is Stronger!?" My son loved these books when he was in elementary school and would diligently buy them with his allowance. I'm selling them now because he no longer needs them. There are no tears, but they were well-loved, so there are some minor folds. Reading is good for the body and mind, unlike smartphones and tablets. How about for your child? Thank you.
