Milwaukee INKZALL™ Black Chisel Tip Jobsite Marker is specially designed to meet the demands of tough jobsite conditions. This marker features a clog-resistant chisel tip that effortlessly writes on rough surfaces like OSB, cinder block, and concrete. It performs reliably even on dusty, wet, or oily surfaces, ensuring your markings stay clear and visible. The quick-drying ink minimizes smudging, while the marker itself resists drying out when left uncapped. For added convenience, the INKZALL™ marker includes a built-in hard hat clip and a lanyard hole, making it easy to keep within reach throughout your workday. Model Number: 48-22-3103
