A set of 2 books: CardonDellsa Education's homework books and Oxford's activity books for young children learning English for the first time. Both are unused and have no writing in them, but... the bottom of the books are wavy, wrinkled, and stained... The cap of a bottle of tea suddenly came off, and this is what happened. The stains are noticeable, but I think there's no problem with practicing, so please consider purchasing if you don't mind. Please purchase after agreeing to the condition. m(_ _)m No individual sales. Thank you for looking.
