Chalky balls, make sure to clean them before you play with them. Otherwise, pretty solid, though the Nittaku balls are far superior for about 20 cents more a ball.

For me the best ball out there! Despite its price etc. Very consistent, does not break. I really like it the best out of all the balls I tried.
