This is a 36-volume DVD set of Hoshi Mitsuru's Talent Education Excellent Flashcards. It comes with an activity sheet. I bought it for my son, but he hardly used it, so it has been stored at home. It is a complete set of all 36 volumes in the series. It is generally in good condition, but one case has a broken bottom. This does not affect storage or organization. This is a popular product, so please feel free to comment if you are interested.
