Common questions

Will these markers work on wet or oily corrugated boxes?
Yes. The water-resistant permanent ink is specifically formulated to mark wet and oily surfaces, making it ideal for damp warehouse environments, outdoor storage areas, and pallets that have come into contact with moisture or oils during handling.
How quickly does the ink dry on corrugated surfaces?
The ink dries quickly to prevent smudging on cardboard and corrugated boxes. This rapid drying time reduces marking bottlenecks in high-volume shipping rooms and allows for immediate box stacking without ink transfer.
Can I use these markers on surfaces other than corrugated boxes?
Absolutely. The Magnum™ marker marks corrugated, wood, metal, foil, plastic, and leather, making it versatile for multi-surface warehouse environments including metal racks, plastic pallets, and wooden crates.
Why is the broad magnum tip better for warehouse marking?
The magnum tip creates bold, highly visible marks that are easily read from a distance, critical for sorting, routing, and inventory verification in fast-paced fulfillment centers. Larger marking area reduces application time and ensures compliance markings are unmistakable.
