General-purpose permanent paint marker makes clear, bold markings on almost any surface. Quick-drying, oil-based paint withstands indoor and outdoor environmental conditions, ensuring fade-, chip-, smear-proof performance. Bright, vibrant colors are ideal for color-coding or permanently labeling inventory, assemblies, tools, finished products or works-in-progress. Handy clip-cap screws on for secure closure and ensures the marker will not roll off surfaces. Valve-action mechanism prevents paint in barrel from drying when cap is left off. High-capacity, heavy-duty aluminum barrel features a threaded end can be screwed into a jig or similar apparatus for continuous, machine-based identification applications. Replaceable bullet tip. Drying time: 25 to 35 seconds.
