This is a set of 12 books from the Disney English System Main Program. Purchased new in 2019. I bought this set, but I already had these, so I'm selling them. I've flipped through all of them, and there are some page-turning wrinkles and touch pen marks, as shown in the 7th photo. Book 1 has a small tear on the edge of the page. I think they are in relatively good condition, but please understand that this is a personal inspection. If you have any other questions, please ask, no matter how small!
