The Rainbow Chalk Steelwriter is a 5mm broad nib marker pen designed specifically for temporary, precise marking on steel and metal surfaces. Its water-based, chloride-free ink dries in one minute, resists light moisture, and wipes away cleanly without staining—even after galvanizing. Trusted by fabricators and welders, it combines industrial-grade durability with a safe, non-toxic formula for professional use in busy workshops and job sites.
