Mini Billiard Balls - Group of Twelve

I find these mini pool balls aesthetically satisfying in the same way I do old clay marbles -- just great looking. This is not a complete set, and they are pretty worn, but I'd just throw them in a bowl to enjoy looking at them, and toss around every now and then. I believe the 8 ball is from a different set and is more of a bouncy rubber ball; the others are hard on the inside, I think with rubber skins. 

7/8" in diameter; the 8 ball is 1 1/4" d. Box not included.
