Selling as a set of 4 books. As shown in the 4th photo, there are a few places where the pages are split. Also, as shown in the 5th and 6th photos, there are two places where the pressure of a child's name written in pencil and then erased remains. The name part has been partially processed and hidden in blue. Other than that, there are no other noticeable defects. If you understand that these are used items, thank you for your consideration.
