Good flow, needs careful handling
The ink quality is top-notch and very resistant to oil and water. Just be careful when refilling; it can get messy if you squeeze the bottle too hard. The dropper helps immensely.

Excellent refill solution
Instead of throwing away expensive markers, I just refill them with this. The black is deep and opaque. Highly recommend for anyone doing line drawings or heavy-duty labeling.

Perfect for construction site marking
This ink is incredibly durable. I use it to mark lumber and metal beams on site, and it stays visible even after rain. The large bottle lasts a long time too.

Best bulk ink I've found
We go through a lot of markers in our warehouse. This large bottle saves us money and the red color is vibrant and easy to read from a distance. Will buy again.

No more fading files
I use the blue ink for archiving documents. Unlike water-based inks, this does not fade over time or smear if the paper gets slightly damp. A must-have for office organization.

Great value, slight odor
The ink flows smoothly and dries very quickly. It is truly waterproof as advertised. The only downside is a mild chemical smell when first opening the bottle, but it dissipates fast.
Q: Does this come with a funnel for refilling?
A: The package includes a precision dropper which makes refilling easy and mess-free. A separate funnel is not included but is generally not needed with the provided dropper.
Q: Is the ink safe for use on children's art projects?
A: While the ink is non-toxic once dried, it is designed for industrial and office use. We recommend supervising children during use and ensuring proper ventilation due to the oil base.
Q: Can this ink be used on plastic surfaces?
A: Yes, this oil-based ink adheres well to most non-porous surfaces including plastic, metal, and glass, provided the surface is clean and dry before application.
Q: What is the shelf life of the ink once opened?
A: If the cap is sealed tightly after each use to prevent evaporation, the ink typically remains usable for up to 24 months. Store in a cool, dry place away from direct sunlight.
Q: How do I clean the nozzle if it gets clogged?
A: You can clean the nozzle by wiping it with a cloth soaked in a small amount of rubbing alcohol or the specific marker cleaner sold separately. Avoid using water as it may not dissolve the oil base effectively.
