This is a valuable Shinjo Tsuyoshi (Hokkaido Nippon-Ham Fighters manager) stamp ball, and I'm offering it for sale to someone who truly wants it. The listing is for the ball only. If you'd like the case as well, it's an additional 500 yen. Please comment if you'd like the case. Shinjo-kantoku doesn't sign autographs after retiring, so this is quite valuable (apparently, he uses a stamp instead of a signature).
