Perfect for construction site marking
This ink holds up incredibly well on rough surfaces. Even after rain, the marks remain visible. Great value for the large bottle size.

Vibrant colors
The red and blue are very vibrant. The black is deep and opaque. One bottle lasts a long time since you only need a few drops to refill.

Great for crafting projects
Works well with my custom marker setups. The oil base means it sticks to glossy surfaces better than water-based inks I've tried before.

True waterproof claim
Tested this on cardboard and plastic. Once dry, water beads right off without running the ink. Exactly what I needed for outdoor labeling.

No more dried out markers
Saved a whole set of expensive markers with this refill. The dropper makes it easy to add just the right amount without making a mess.

Good flow, dries quickly
I use this for refilling my office broad-tip markers. The drying time is impressive, and it doesn't smear when I highlight over it immediately.
Q: Will this ink work on fabric?
A: While it will adhere to fabric, it is specifically formulated for hard surfaces and paper. For fabric applications, we recommend using inks specifically designed for textiles to ensure flexibility and washability.
Q: Is this ink safe to use on whiteboards?
A: No, this is a permanent oil-based ink designed for porous and non-porous surfaces like cardboard, wood, and plastic. It is not erasable like dry-erase marker ink.
Q: How long does the ink take to dry on plastic?
A: On non-porous surfaces like plastic, the ink typically dries within 30 to 60 seconds depending on humidity and the amount applied.
Q: Can I mix the colors to create new shades?
A: Yes, since all colors share the same oil-based formula, they can be mixed to create custom shades. We recommend mixing small amounts first to test the result.
Q: Does the bottle come with a refill tool?
A: Yes, each large bottle includes a precision dropper to help you easily transfer ink into your marker reservoirs without spillage.
