This chalk is good for use when outside but never at a rock gym. Will use it to refill my chalk ball but when it is in loose form it is very messy. Will not get it again if a chalk ball is available. Not very easy to use.
I thought it would be convenient, and it was cheap enough, but it gets everywhere - more than block chalk does. But it's easy to use, so I guess that's nice. I think I'm going back to blocks when this is done, though.
