The Ultimate chalker was designed and constructed to put your chalk with you when you need it, and to do it effectively and unobtrusively. The Ultimate chalker is not a clip that is held in place entirely by tension. The ultimate chalker is held in place by its unique under/ over the belt and pant design. When the ultimate chalker is new it will conform to the size of your belt and pants each of the ultimate chalkers come with a single piece of master chalk is a stainless steel chalk holder that attaches to the clip with a magnet. Don't shoot without it!!
