Solid industrial choice
Very durable and reliable for heavy-duty marking. The cap seals tightly so the ink doesn't dry out even if left uncapped for a few minutes accidentally.

Perfect for our warehouse needs
We go through hundreds of markers a month in our logistics center, and these are by far the best. The ink dries instantly on cardboard boxes and doesn't smear even if the package gets wet during transit.

Essential for courier services
As a courier driver, I need markers that work in all weather conditions. This one writes clearly on damp boxes and the ink never runs. Highly recommended.

Lasts longer than competitors
These markers seem to last twice as long as the brand we used previously. The broad tip stays intact without fraying, making every label look professional.

Great marker, strong odor
The performance is excellent for labeling shipments. My only note is that the oil-based ink has a strong smell, so ensure good ventilation when using it indoors.

Truly waterproof and bold
I tested this on plastic bins and metal shelves. The line is thick, dark, and completely waterproof. It hasn't faded after being left in the sun for weeks.
Q: Does the broad tip fray easily after extended use?
A: No, the tip is made from durable felt designed to maintain its shape and line width even after extensive writing on rough cardboard.
Q: Is the ink toxic or safe for use around food packaging?
A: While the ink is non-toxic once dry, this marker is designed for industrial shipping labels and should not be used to mark surfaces that come into direct contact with food.
Q: Will the ink fade if packages are stored outdoors?
A: The ink is formulated with high UV resistance to prevent fading, making it suitable for packages that may be exposed to sunlight during transport or storage.
Q: Can this marker write on glossy plastic surfaces?
A: Yes, the oil-based formula adheres well to non-porous surfaces like glossy plastic, metal, and glass without smudging.
Q: How do I remove the ink if I make a mistake?
A: Since the ink is permanent and waterproof, it requires a solvent like rubbing alcohol or acetone to remove it from most surfaces before it fully cures.
