Bold and clear lines
The broad tip is exactly what I needed for making signs on cardboard and wood. The black ink is very opaque and covers well even on slightly textured surfaces.

Great flow, strong smell initially
The marker writes very smoothly on plastic and glass surfaces. My only minor complaint is that the oil-based ink has a slight chemical smell when you first open it, but it dissipates quickly once dry.

Perfect for industrial labeling
I use these markers daily in our warehouse for labeling metal crates. The ink dries almost instantly and hasn't faded even after being exposed to rain. The large tip makes it easy to read from a distance.

Truly waterproof
I tested this on a flower pot and left it outside during a storm. The writing remained perfectly crisp and did not run at all. Highly recommend for outdoor projects.

Best marker for construction sites
We bought a box of these for our construction team. They write on dusty concrete blocks and wet lumber without any issues. The high capacity means we aren't replacing them every week.

Good but cap can be tight
The marker itself works great and the ink lasts a long time. However, the cap is sometimes very difficult to snap back on tightly, which worries me about the pen drying out if not sealed properly.
Q: Is this safe to use on children's toys?
A: While non-toxic when dry, this is an industrial-grade permanent marker intended for hard surfaces. We do not recommend it for items that children might chew on or put in their mouths.
Q: Can this marker be used on wet surfaces?
A: Yes, the oil-based formula allows it to adhere to damp surfaces like wet wood or stone, though drying time may be slightly longer than on dry surfaces.
Q: How long does the ink last if left uncapped by accident?
A: If left uncapped for more than an hour, the tip may begin to dry out. We recommend recapping immediately after use to maintain the high-capacity ink flow.
Q: Is the ink removable from glass?
A: Once dried, the ink is permanent on glass. It can typically only be removed using strong solvents like acetone or specialized graffiti removers.
Q: Does this come in other colors?
A: This specific listing is for the Black color only. We do offer red, blue, and white variants in separate product listings.
