Marxman

MarXman is a unique tool designed to quickly and easily mark almost any surface with one push. Instead of using a drill bit, a bradawl, or sharpening your pencil and searching for the mark you made, MarXman does the job for you. It simply and accurately releases a burst of bright chalk spray, which clearly marks your reference points, making all other marking devices redundant.

Each pen contains 250+ bursts of removable green pigment. Suitable for brick, metal, wood, pebbledash, porcelain and ceramic.
