Perfect for warehouse labeling
These markers are incredibly bold and dry almost instantly. I use them to label metal shelves in our warehouse, and the ink hasn't faded or smudged despite the humidity.

Good for rough surfaces
Works great on concrete and brick. The broad tip covers a lot of ground quickly. Took off one star because the cap can be a bit tight to remove sometimes.

Great flow, strong smell
The ink flow is consistent and covers dark surfaces well. Just be aware that being oil-based, it has a strong chemical smell, so use it in a ventilated area.

Artist approved
I use these for street art projects. The opacity is fantastic even on graffiti-covered walls. Highly recommend for anyone needing a reliable thick black line.

Lasts a long time
The large capacity means I don't have to replace these often. I've been using the same pen for three weeks on daily construction site markings and it's still going strong.

Truly waterproof
I tested this on a plastic bin and ran it under water immediately after drying. The mark stayed perfectly crisp. Excellent quality for the price.
Q: What is the approximate line width?
A: The broad tip typically produces a line width between 8mm and 10mm, depending on the pressure applied and the texture of the surface.
Q: Can this marker be used on wet surfaces?
A: For best results, please ensure the surface is clean and dry before application. While the ink is waterproof once dried, applying it to a wet surface may affect adhesion and drying time.
Q: Is the ink refillable?
A: No, this marker is designed as a single-use unit with a large internal reservoir. Once the ink is depleted, the entire pen should be replaced.
Q: How long does it take to dry?
A: On non-porous surfaces, the ink is usually touch-dry within 30 to 60 seconds. Full curing and maximum water resistance are achieved after 24 hours.
Q: Does this work on glass windows?
A: Yes, the oil-based formula adheres well to glass. However, please note that because it is permanent and waterproof, it may require solvents like alcohol or acetone to remove.
