Why Buy A Mighty Marker

Behind every Mighty Marker is 70+ years of craftsmanship, in-house formula development, custom engineering, and compliance-ready manufacturing. Designed to solve your exact marking challenge.

Built on Craftsmanship Since 1956

That craftsmanship runs deep. Arro-Mark®'s team develops formula chemistry, tests surface compatibility, and validates performance under real industrial conditions. Expertise comes with the marker.

Formulas Developed by Arro-Mark

Every Mighty Marker® formula is proprietary. What's in the marker is developed and manufactured exclusively by Arro-Mark® in Englewood, NJ. That means consistent performance, batch after batch.

Engineered for Your Application

When standard markers don't cut it, come to Arro-Mark® directly. Our team works with you to engineer marker solutions for your surfaces, conditions, compliance requirements, mark size, and color - not a generic substitute.

Compliance? Come to the Source

Low-chloride, MIL-spec, ASTM, nuclear-grade - if your application requires certified documentations, Arro-Mark® has it. We've been supplying compliance-ready markers to regulated industries for decades.
