Paperback books in English, Captain Underpants, set of 2. I purchased these new for extensive reading. I'm selling them now that I've finished reading them. While Japanese translations are available for volumes 1-5 of Captain Underpants, volumes 6 and onward do not have Japanese editions, so you'll need to read the English versions to know the story. This is a set of volumes 6 and 7. I am also selling volumes 1-5 and volume 8 separately. I would be happy if you would take a look at those as well.
