Avery® Marks A Lot Ultra Duty Permanent Markers - Black Ink - 12 Pack

Work through the toughest conditions with these Marks A Lot UltraDuty Permanent Markers. Designed for moments when traditional permanent markers aren't strong enough, these industrial-grade markers are ideal for workshops, warehouses, and construction sites. They are perfect for marking metal pipes, plastic bins, wood pallets, and concrete walls.

The sturdy tip writes clearly on wet, dusty, oily, and abrasive surfaces without clogging. The flat and angled 0.5mm chisel tip allows for varying line widths, making it easy to switch from thin to bold lines on the spot.

These markers are great for outdoor use, with specially engineered black ink that is resistant to water, abrasion, and smearing while remaining bold and visible. The industrial ink won't dry out even if the cap is left off for up to 72 hours.

For added convenience, these markers feature a built-in clip to prevent rolling and can be looped into lanyards for extra security.
