Perfect for our construction site labels
We use these refills for marking steel beams and concrete blocks. The ink sticks incredibly well even in dusty conditions and doesn't wash off when it rains. Great value for the volume provided.

Truly waterproof and durable
I tested this on a plastic crate that sits outside. After three weeks of sun and rain, the markings are still crisp and clear. Highly recommend for any industrial application.

Cost-effective bulk solution
Buying individual markers was getting expensive. This large bottle allows us to refill dozens of pens for a fraction of the cost. The blue color is very vibrant.

Good flow, strong odor
The ink flows smoothly into my large tip markers without clogging. The only downside is the strong chemical smell, so make sure to use it in a ventilated area. Otherwise, excellent product.

Works great on glass
Used this to label glass panels in a warehouse. It adheres perfectly and wipes off only with specific solvents, which is exactly what we needed for permanent identification.

No fading after months
We marked some equipment last winter, and the ink has not faded at all despite being exposed to direct sunlight. The non-fading claim is definitely accurate.
Q: Can this ink be used in standard permanent markers?
A: This ink is specifically formulated for large tip oil-based markers. It may be too thick for standard fine-point felt tips and could cause clogging.
Q: Is the ink safe to use on food packaging?
A: No, this is an industrial-grade oil-based ink and is not certified for direct contact with food or food packaging materials.
Q: What is the shelf life of the ink once opened?
A: If kept tightly sealed in a cool, dry place away from direct sunlight, the ink typically remains usable for up to 24 months after opening.
Q: How do I remove this ink if I make a mistake?
A: Since the ink is waterproof and oil-proof, water will not work. You will need to use a solvent such as acetone, alcohol, or a dedicated industrial ink remover.
Q: Does the bottle come with a nozzle for easy refilling?
A: Yes, each bottle includes a precision dropper nozzle to help you transfer the ink cleanly into your marker reservoirs without spilling.
