The edding 8870 drill hole marker spray from Marxman is a unique tool designed to quickly, easily and precisely mark holes on almost any surface with just one spray. Precisely marking holes in a workpiece is often a challenge. Either the marker tip is too short or too wide, the marking is not clearly visible on the surface or it is very difficult to use. With the new edding 8870 from Marxman, these challenges are a thing of the past. The marker uses a patented pump mechanism to spray green chalk to create precise, non-permanent markings. Simply place the tip on the drilled hole, press and you're done.
