Unopened and opened cans of 2 tennis balls approved by the Hanshin Tigers, and 1 tennis ball. 1 ball was used after opening the can. 1 ball remains, unused. The balls are ブリヂストン XT8. Acquired several decades ago, 1 was used, and then stored in a closet for a long time, so please refrain from purchasing if you are concerned. How about it, Tigers goods collectors?
