The sticks are Sanwa Jlws.
The ball tops are Sanwa white mesh balls.
If you'd like to spend $12 (each) for a ball (standard balls are $2) that has a pattern that is only viewable by sticking it in your eye, then I highly recommend them.
Seriously though, the mesh balls are nice, it's just the pattern is not very visible on the white ones. Standard white tops would probably be just as nice except they would have the mold line on them.
Boy, that was a long answer to a simple question.
