Bold and durable
The thick tip makes writing large tracking numbers incredibly easy. The black is very deep and opaque, making it readable from a distance. Highly recommend for logistics teams.

Lasts a long time
I bought these for marking inventory crates. One marker lasts much longer than the water-based ones we used to buy. The cap seals tightly so the ink doesn't dry out between uses.

Perfect for our warehouse needs
We go through hundreds of markers a month for shipping labels, and these are by far the best. The ink dries instantly on cardboard boxes and doesn't smear even if it gets rained on during delivery.

Solid performer
Very reliable marker for daily shipping tasks. The flow is consistent, and I haven't encountered any dried-out tips right out of the box. Would purchase again.

Excellent adhesion on plastic
Not only does this work on boxes, but it also writes clearly on our plastic bins without wiping off easily. It takes a solvent to remove, which is exactly what we need for permanent labeling.

Great quality, strong smell
These markers work exactly as described. They are waterproof and fade-resistant. The only downside is the strong oil-based smell, so make sure to use them in a ventilated area.
Q: Can I refill these markers once they run dry?
A: These markers are designed as disposable units and do not have a refillable mechanism. Once the ink is depleted, the entire unit should be recycled according to local regulations.
Q: Will this ink bleed through standard corrugated cardboard?
A: While the ink is thick and bold, it is designed to sit on the surface. On very thin or low-quality cardboard, slight show-through may occur, but it generally does not bleed through standard shipping boxes.
Q: Is this marker safe to use on food packaging?
A: No, this is an industrial-grade oil-based marker and is not certified food-safe. It should only be used for external labeling on shipping containers and non-food contact surfaces.
Q: Does the cap have a clip for attaching to a clipboard or pocket?
A: Yes, each marker features a sturdy integrated clip on the cap, making it easy to attach to pockets, clipboards, or lanyards for easy access during work.
Q: How long does the ink take to fully cure before it is waterproof?
A: The ink is touch-dry within 3 to 5 seconds on porous surfaces like cardboard. For full water resistance and chemical stability, we recommend allowing 24 hours for complete curing.
