None lost chalk and concentration. Thanks to this pocket chalk holder, you keep your chalk to the belt.
A nice little pocket in leather that just attaches on your belt. Very easy to use, you just have to pick up your chalk when you need it. As he told us in the video "what's in your case*", Stephan Cohen keeps it on him all times when playing billiard. Try it and you like it! Chalk not included. * You can watch this video-clip "What's in your case" on the home-page
