Milwaukee INKZALL™ extra large jobsite markers are optimized for jobsite conditions. The extra large chisel tip produces bigger and bolder writing for clear visibility. The durable tip is designed to write on dusty, wet or oily surfaces in a clog resistant manner which results in clean, continuous marking. The quick dry ink reduces the likelihood of smearing after use. The marker can also be left without a cap on for up to 72 hours and remain completely functional.
