The kids on my son's and daughter's soccer teams pick these up by the hundreds, if not thousands, off of the soccer pitch before they play a game.
They're not a nuisance, just a curiosity. They're roughly 5.5mm in diameter and made out of a very hard and dense plastic. A handful of them has a bit more heft to than what one would expect with other plastics. Also, they come in quite a number of colors. Green and yellow seem to be the most prevalent ones.
I wouldn't ask, except they're quite uniform in shape (none of them are "out of round"), and they are as hard as nails.
Perhaps they're used in place of darts for a blowgun?
