Description

The Mighty Marker® MM-38 is engineered for professionals who need precision marking without compromising sensitive metal surfaces. Its low corrosive, low halogen, low chloride formula, containing less than 150 ppm chlorides and halogens, is designed to protect stainless steel and other sensitive metals from corrosion, contamination, and tarnishing, unlike standard paint markers that can damage these surfaces over time.

The reversible 2.3mm double-sided bullet nib delivers clear, legible, professional marks. A valve-action mechanism keeps paint flowing consistently and won't dry out even if the cap is left off.

Manufactured in the USA by Arro-Mark®, 70+ years of industrial marking craftsmanship.
