The Marxman Standard Shallow Marking Pen clearly and accurately marks a fixing point on your workpiece with a bright green dot. It will work on most materials, including brick, wood, metal, ceramic, porcelain and pebbledash, so you'll be ready to cut or drill with precision on a variety of jobs. This pen dispenses 250+ bursts of green pigment, so you only need one in your toolbox to see you through plenty of drilling and mounting tasks. Using it is easy too, as all you need to do is push it on the surface and it will leave a single dot with no runs. The fluorescent colour means you'll be able to see it clearly, even at a distance.
