손안의 당구작전판, 3쿠션 복기용 노트(Billiar

After placing and capturing a billiard ball, it can be used as a billiard note to record the location of the ball, or when explaining the arrangement during a game or when placing the ball during a replay after a game.

I made this with the idea of ​​using it instead of the magnetic board used by PBA players (I was already using a board with good functions as an electronic pen... As expected...)
As an individual makes it alone, it lacks a lot... I made it for myself anyway, and I'm using it well, so I thought I'd share it.

Until now, I used to record the three-cushion biggie in a blank notebook or a printed billiard table notebook, but now I am going to save it by saving it on my phone and writing it down with a note pen.
