This is a Harry Potter educational material. It includes quizzes, English word games, coloring pages, and number puzzles, allowing children to play with Harry Potter characters. There are no markings inside, but there is a mark from a sticker being removed on the upper right corner of the cover. Please consider this if you are interested. I am selling this as a set of 3 books, but individual books can also be sold. Please let me know in the comments if you are interested in purchasing a single book. If you have any questions, please feel free to ask ^ ^ Thank you.
