KONAMI Baseball Card Field of Nine Not for Sale 12-Card Set

A set of 12キラ (kira - shiny/holographic) cards from the Field of Nine card game, originally won as a prize.
There is one player from each team, making a total of 12 cards.
I don't remember which contest I won them in.
I am not familiar with this card game, so I have priced them based on other listings.
They have never been used and have been stored indoors.

No claims, no returns.

Price negotiation is not possible.
