Perfect for industrial labeling
These markers are incredibly bold and dry almost instantly. I use them for labeling metal pipes in the warehouse, and the ink hasn't faded or washed off despite exposure to moisture.

Reliable for outdoor projects
Used this to mark garden stakes and outdoor equipment. It has been raining for weeks and the markings are still crisp and clear. Highly recommend.

Lasts forever on plastic bins
I bought these for our moving boxes and storage bins. The black is deep and opaque, covering up old labels easily. Truly waterproof as claimed.

Great ink flow, strong smell
The line quality is excellent and very thick as advertised. Just be aware that because it is oil-based, there is a strong chemical odor, so use it in a ventilated area.

Best coarse tip I've found
The tip is sturdy and doesn't fray even after heavy use on rough concrete surfaces. High capacity means I haven't had to replace it yet.

Good but bleeds through paper
Works amazing on non-porous surfaces like glass and metal. However, do not use on standard printer paper; the ink bleeds right through to the other side.
Q: Can the ink be removed from glass if I make a mistake?
A: Once dry, the ink is permanent. You can usually remove it from non-porous surfaces like glass using rubbing alcohol or a specialized solvent cleaner.
Q: Will this work on wet surfaces?
A: For best adhesion and drying results, we recommend applying the marker to a clean, dry surface. Applying to wet surfaces may cause smearing or poor adhesion.
Q: Does this come in other colors besides black?
A: This specific listing is for the Black variant only. We do carry red, blue, and white in separate product listings within our store.
Q: How long does the tip last before it wears down?
A: The coarse tip is designed for durability. With normal usage on various surfaces, one pen typically lasts for several hundred feet of continuous line.
Q: Is this marker safe to use on food packaging?
A: No, this is an industrial oil-based marker and is not certified food-safe. It should only be used on external packaging or non-food contact surfaces.
