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. Make sure to seal it properly after each use.

Lasts a long time
The high-capacity ink reservoir is no joke. I've been using this same pen for three weeks on various construction materials and it still feels like it has plenty of ink left.

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

Great flow, strong smell
The marker writes very smoothly and the line is thick and bold as advertised. My only complaint is the chemical smell is quite strong, so I only use it in well-ventilated areas.

Best marker for glass
I needed something to write temporary inventory numbers on glass panels. This writes instantly, dries fast, and can be removed with alcohol when needed. Perfect balance.

Truly waterproof
I tested this on a plastic garden pot and left it out in the rain for a week. The marking didn't fade or run at all. It's exactly what I needed for outdoor projects.
Q: Will this write on polished stainless steel?
A: Yes, oil-based ink is specifically formulated to adhere to non-porous surfaces like polished stainless steel, glass, and plastics.
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: Is the ink refillable?
A: No, this specific model is designed as a disposable unit with a high-capacity reservoir and cannot be refilled.
Q: How do I remove the ink if I make a mistake?
A: Before the ink fully cures, it can sometimes be wiped with a rag soaked in mineral spirits or rubbing alcohol. Once cured, removal may require abrasive cleaning methods.
Q: What is the shelf life of the pen if unopened?
A: An unopened pen typically has a shelf life of about 2 years from the date of manufacture if stored in a cool, dry place with the cap sealed.
