Our INKZALL Extra Large Chisel Tip Jobsite Markers are optimized for job site conditions. The extra large chisel tip allows you to write bigger and bolder for clear visibility. The construction marker features a durable tip that is designed to write on dusty, wet or oily surfaces. It is clog resistant, providing you with clean, continuous marking. Quick Dry ink also reduces the likelihood of smearing after use. The permanent marker can be left without a cap on for up to 72 hours and remain completely functional. Our MILWAUKEE INKZALL markers showcase our relentless mission to provide you with innovative solutions and commitment to best-in-class durability.
