Durable and reliable
I've dropped these pens multiple times on concrete, and they still work perfectly. The cap seals tight, so the tip never dries out even if left uncapped for a minute or two by accident.

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 rains during pickup. Highly recommend for logistics teams.

Truly waterproof and bold
I used this to label some outdoor storage bins. After two weeks of sun and rain, the writing is still perfectly legible. The thick tip makes it easy to write quickly without pressing hard.

Good value for bulk buying
Bought a box for my small business. They last a long time and the line width is consistent. Took off one star because the cap can be a bit stiff to remove initially, but it loosens up with use.

Great marker, strong smell
The performance is excellent; it writes on almost any surface including plastic tape. My only complaint is the oil-based ink has a strong odor, so make sure to use it in a ventilated area.

No more faded labels
Previously, our labels would fade after a few months in the truck. These markers solve that problem completely. The black is deep and opaque, making barcodes and addresses easy to scan and read.
Q: How long does the ink take to dry completely?
A: On most porous surfaces like cardboard, the ink is touch-dry within 3 to 5 seconds. On non-porous surfaces like plastic or metal, we recommend allowing 10-15 seconds for full curing before handling.
Q: Is the ink toxic? Is it safe for use around food packaging?
A: While the ink is non-toxic once dry, this product is intended for industrial and logistics labeling, not for direct contact with food. We do not recommend using it on surfaces that will directly touch consumable items.
Q: Can I use this marker on glossy plastic shipping tape?
A: Yes, absolutely. One of the main features of this marker is its ability to adhere to non-porous surfaces like glossy tape, metal, and glass without wiping off easily.
Q: Will this ink bleed through standard corrugated cardboard boxes?
A: Generally, no. The oil-based formula is designed to sit on the surface and dry quickly. However, on very thin or low-quality cardboard, slight show-through might occur, but it will not smear the other side.
Q: Does the tip wear down quickly with heavy daily use?
A: The tip is made from durable felt designed for high-volume writing. With normal daily use in a warehouse environment, a single marker typically lasts for several weeks before the tip begins to fray significantly.
