Baseball Hardball

Hardball

Mitsubishi Kawasaki, Daiwa Bank, TOSHIBA
Denden Shikoku, Kochi Prefecture High School Baseball Federation
Tokai University, High School Game Ball, TOKAI
Japan High School Baseball Federation, Dragons
Set of 10

These are practice and game balls for each team.
Some teams have since disbanded, making these rare.
This was before Denden Shikoku became NTT.

I received these about 40 years ago when I visited various ballparks.

The leather has deteriorated, so they are not actually usable,
but they are suitable for light catch.

For old baseball fans, please consider!
