Doraemon Chibi Maruko-chan Learning Series Respectful Language Classroom Understanding Maps Well 100 Four-Character Idioms Thank you for viewing. This is a set of 3 learning manga books. These were used by a child, so there is some wear and tear from use. Please check the photos for damage. I don't think there are any writings, but I apologize if I missed something. I didn't check each page individually. From a quick look, there were no writings. There is a feeling of use! Thank you!
