Truly waterproof
I accidentally left a marked box outside in the rain, and the writing didn't run or fade at all. Exactly what I needed for outdoor storage labeling. Highly recommended for logistics teams.

Good grip and flow
The barrel is thick enough to hold comfortably during long shifts. The ink starts flowing immediately without needing to shake it vigorously. A solid workhorse pen.

Bold and durable
Great pen for marking up items that need to stand out. The line is very thick and dark. I took off one star only because the cap can be a little tight to remove quickly, but that also means it doesn't dry out easily.

Long-lasting ink
One pen lasts much longer than the standard office supply store brands. The oil-based formula seems to hold more ink, making it cost-effective for high-volume shipping departments.

Perfect for our warehouse needs
We go through hundreds of markers a month for labeling boxes, and these are by far the best. The ink flows smoothly even on rough cardboard, and it dries instantly so there's no smudging when we stack packages.

Best marker for plastic bins
We use these to label our reusable plastic tote bins. Most water-based markers wipe right off, but this oil-based ink sticks perfectly and survives multiple washes.
Q: How do I refill this pen once the ink runs out?
A: This specific model is designed as a disposable unit and cannot be refilled. However, due to its large ink capacity, it typically lasts significantly longer than standard felt-tip markers.
Q: Does the strong smell typical of oil markers apply to this product?
A: We have formulated this pen with a low-odor technology. While there may be a faint scent characteristic of oil-based inks, it is much milder than traditional industrial markers.
Q: Can this marker write on glossy plastic surfaces?
A: Yes, the oil-based formula is designed to adhere well to non-porous surfaces like glossy plastic, metal, and glass, provided the surface is clean and dry.
Q: What is the exact width of the line this pen produces?
A: The large tip generally produces a line width between 5mm and 7mm, depending on the pressure applied and the texture of the surface being written on.
Q: Is the ink toxic or safe for use around food packaging?
A: While the ink is non-fading and durable, it is not certified as food-safe. We recommend using it only on the exterior of packaging and avoiding direct contact with food items.
