Survives the elements
I use these to label boxes for storage units. After six months in a humid garage, the writing is still perfectly black and readable. Definitely lives up to the waterproof claim.

Bold and durable
Great marker for writing on dark surfaces or plastic bins. The line is very thick and opaque. I took off one star only because the cap can be a little tight to remove quickly if you have wet hands, but the seal keeps the ink fresh.

Best value for money
The ink volume is impressive. One marker lasts us about two weeks of heavy daily labeling. The bold black line makes addresses easy to read for drivers, reducing delivery errors.

No more faded labels
Our previous markers would fade within weeks under the warehouse lights. These oil-based ones are still crisp after months. The quick-drying feature is a lifesaver for our high-volume shipping days.

Perfect for our warehouse needs
We go through hundreds of markers a month labeling packages. These are fantastic. The ink dries instantly so there's no smudging when we stack boxes, and it stays legible even after being out in the rain during delivery.

Good for industrial projects
Bought this for marking lumber and PVC pipes. It writes smoothly on rough textures where other pens skip. Just make sure to cap it tightly immediately after use, or the tip can dry out.
Q: Can this be used in freezing temperatures?
A: Yes, the oil-based ink remains fluid in cold conditions, making it suitable for outdoor labeling even in winter weather.
Q: Is the ink toxic if it accidentally gets on skin?
A: While the ink is designed for industrial durability, it is generally safe for incidental skin contact. We recommend washing with soap and water or using rubbing alcohol to remove it. It is not intended for use on skin.
Q: How long does the tip last before it frays?
A: The thick fiber tip is reinforced for durability on rough surfaces like cardboard. With normal use, it typically maintains its shape for the life of the ink cartridge.
Q: Will this marker write on glossy plastic shipping envelopes?
A: Yes, the oil-based formula adheres well to non-porous surfaces like glossy plastic, metal, and glass without smearing.
Q: Does it come in a pack of 12?
A: This listing is for a single unit. However, we do offer bulk packs of 12 and 24 at a discounted rate on our store page under the 'Bulk Supplies' section.
