Description

    The Mighty X Marker® PM-45 features a reversible dual-sided nib, bullet on one side, chisel on the other, so you can switch between precise detail work and bold, high-visibility marks without reaching for a second marker. Its alcohol-based formula is Xylene-Free and HAPS-Free, delivering the same industrial-grade permanence as our oil-based line, built for indoor and enclosed-space use.

    Opaque, permanent paint writes on metal, glass, plastic, painted steel, stainless steel, ceramics, and wood. Water Resistant, weather resistant, and resistant to fading and abrasion, marks hold up indoors and outdoors, trusted across fabrication, welding, aerospace, automotive, and metalworking environments. The marker ships with one nib installed; replacement nibs are available separately.

    Manufactured in the USA by Arro-Mark®, 70+ years of industrial marking craftsmanship since 1956, and as the manufacturer, we can support custom requirements when you have them.
