Description

The Mighty Marker Fine Line gives you tight control for detailed work. It’s a favorite for welders and fabricators laying out cut lines, plumbers marking fittings, and technicians labeling components, panels, and parts where a standard marker is too broad.

The oil-based opaque paint writes on metal, plastics, rubber, wood, masonry, and glass—even if the surface is wet or oily—and dries fast to reduce smearing. Built for indoor or outdoor use with long-term resistance to fading, abrasion, chemicals, and UV.

Made in the USA by a family-owned manufacturer with 70+ years of industrial marking craftsmanship.
