What is the differences in bowling balls?

why are some more expensive? is it just looks or is there something else?

Finger hole size too, and the material it's made of, and the density, and then some are special made so they're more expensive (like those clear ones that have things inside them).

Maybe the age, size, color, or weight. I hope i helped you! :) :)

There weight, or color

what are you talking about ? american bowls or the true world of bowls played on a lawn or green ?

I don't no yes I do the color, weight, hole size, king, and where it was made

weight, color, and finger-hole size. (:
