| Description | |
|
The Mighty Marker® MM-99 Rolling Ball Tip Marker is built for surface conditions that destroy standard paint markers. A rear pump mechanism builds internal pressure inside the metal barrel, so all 30mL of paint gets used, with no wasted product and no premature dry-out. Press the pump once and hold the marker upright while writing for best results. The steel rolling ball point tip, a medium #3, 2.4mm line width, glides effortlessly across smooth, abrasive, and uneven surfaces, delivering controlled, legible marks in wet, oily, rusty, and otherwise contaminated conditions, even underwater, where felt or fiber tips quickly degrade. Industrial-grade permanence: thick, bright, opaque, and weatherproof marks resist direct sunlight and stay legible outdoors for 10+ years. Manufactured in the USA by Arro-Mark®, 70+ years of industrial marking craftsmanship. |
