A practical book with a DVD that teaches the basics of badminton and how to level up. - Title: Doubles Bible: Basic Edition - DVD: Included - Title: Doubles Bible: Level Up Edition - Authors: Kumiko Ogura & Reiko Shida Price: 1,900 yen each + tax Set of 2: 3,800 yen total + tax Thank you for viewing. I have played the DVDs several times. There are fine scratches on the surface, but they do not affect playback. The text itself is in beautiful condition as I haven't had much time to read it. I have purchased several badminton-related texts, but I think this one is the most practical. I hope to sell it to someone who understands that it is a used item.
