This was Japan's first "exchange game between professional and university select teams" in baseball, jointly hosted by Nippon Professional Baseball (NPB), the professional baseball organization, and the All Japan University Baseball Federation (JUBF), an amateur organization. It was held on November 22, 2009, at the Tokyo Dome. The university select team included many players who later became active in professional baseball! This is a must-see item for those who collect baseballs‼️ The ball is new and has no yellowing. I don't think it will be available on the market anymore. No price reduction is possible, but thank you for your understanding.
