They are actually harder than the advertised lacrosse balls. In fact, they're about as heavy as they come. they give absolutely NOTHING. They might as well be steel. Honestly it would be cool. In any case, you must be aware of this before buying them because they will dig VERY deep and if you are not used to it, it will surprise you. honestly there is really nothing more to say about it. they are round hard balls. I doubt these things will ever really break or get damaged. Definitely worth $10.
