Hello everyone, do you ever notice how the thin-line chalk always seems to break every time you even think about bearing down on it or drop it or tap it against something just a bit too hard? A while back I saw some fellas do a little something about that problem. They would spray paint both sides of the chalk before using it in their holder. Not a thick layer of paint but just enough on both sides to keep it together a bit better than it does in it's natural state. Just a little something I thought I'd pass on. Regards, aevald
