Overall, the discs are in very good condition. Three discs show light signs of use and are pictured in the photos for reference. All remaining discs are in excellent condition. Please note that the Vocabulary DVD (the case with the dog on the cover; see photos) is missing 1 disc. This is the only missing disc in the set. Also, based on other listings, this set may have originally included a book. If so, it is not included.
