13ml - Professional Marking Tool Marxman

The Marxman marking tool commonly called the Marxman pen as seen on TV from BBC's Dragon's Den is a handheld device used in construction to accurately mark drill points through walls, ceilings, and floors. It features approximately 250 bursts of bright green chalk to mark the surface up to 50mm depth with the required drill hole point, creating precise marks on almost any surface. This tool saves time, improves accuracy, and is particularly useful for installing pipes, cables, and fixtures in construction and renovation projects.
