Built for the demands of professional electricians and contractors, the Milwaukee INKZALL™ Black Fine Point Marker (48-22-3100) is engineered to perform where standard markers fail. Its clog-resistant fine point tip writes reliably on rough, dusty, wet, and oily surfaces — from concrete and cinder block to OSB and conduit — making it an essential tool for marking layouts, labelling panels, and annotating materials on any job site. Quick-drying ink reduces smearing, while the anti-roll body, built-in hard hat clip, and tether-ready lanyard hole keep it accessible and secure throughout the work day.
