This is a Step-by-Step set from the Disney English System (DWE). I received this as a gift, originally purchased in 2011. I have not used it. [Guidebooks] 4 books, appear to be unused. They are in clean condition with no folds. [DVDs] 12 discs Operation not confirmed. Some cases are cracked due to aging (see photos). Discs 8-12 are unopened. Discs 1-7 have been opened, and the cases are cracked, but it appears they haven't been used much. Please purchase only if you know how to use the system. I have not used this at all, so I don't know how to use it or what accessories are included. I am only selling what is shown in the photos, but there may be other materials available if you look for them. Please send a message if you have any questions. Purchased in Japan in 2011, official product.
