Best marker for dark surfaces
Although this is black ink, the opacity is so high it covers minor scratches on dark machinery beautifully. The coarse tip makes quick work of large text.

Truly waterproof
I tested this on a plastic bin that sits outside in the rain. After three weeks, the marking is still crisp and clear. It definitely lives up to the waterproof claim.

Perfect for industrial labeling
I use these markers daily in our warehouse for labeling metal crates. The ink adheres perfectly to rough surfaces and doesn't smear even when handled roughly. Highly recommended for heavy-duty tasks.

Lasts a long time
The large capacity means I don't have to replace this often. I've been using the same pen for two months of daily crafting projects and it still has plenty of ink left.

Great ink flow, strong smell
The marker writes very smoothly and the line is bold and consistent. My only complaint is the chemical smell is quite strong, so I recommend using it in a well-ventilated area.

Good but dries out if cap is loose
The marker works great when fresh, but if you don't click the cap on tightly every single time, the tip dries out quickly. Just need to be careful with storage.
Q: Does this contain xylene or toluene?
A: Our oil-based formula is free from xylene and toluene, making it safer for general indoor use with proper ventilation.
Q: What is the exact width of the line produced?
A: The coarse tip typically produces a line between 8mm and 10mm wide, depending on the pressure applied and the texture of the surface.
Q: Is the ink refillable?
A: No, this specific model is designed as a disposable unit with a large internal reservoir and cannot be refilled.
Q: Can this marker be used on wet surfaces?
A: While the ink is waterproof once dried, we recommend applying it to clean, dry surfaces for the best adhesion and immediate results.
Q: Can I remove this ink from glass if I make a mistake?
A: Once fully cured, the ink is permanent. However, fresh marks can be wiped off glass with rubbing alcohol or a specialized adhesive remover before they set.
