Strong smell initially
The ink quality is great and writes on almost anything. There is a slight chemical smell when you first open the refill, but it dissipates quickly once applied.

Excellent flow control
No bleeding or blotching. The oil-based formula provides consistent lines whether I'm writing slowly or quickly. Will buy again.

Saves money and reduces waste
Instead of throwing away the whole pen when it runs dry, I just swap these refills. Easy to install and the large capacity lasts a long time.

Fade-resistant as advertised
I use these for outdoor labeling on plastic bins. After two months in the sun, the writing hasn't faded at all. Highly recommend for durability.

Good capacity, vibrant colors
The blue and red are very vibrant. The black is deep and opaque. Only giving 4 stars because the cap on one refill was slightly loose, but the ink itself is excellent.

Perfect for my industrial markers
These refills fit my big head markers perfectly. The oil-based ink flows smoothly and doesn't skip. Great value compared to buying new pens.
Q: Can I mix these colors to create new shades?
A: We do not recommend mixing different colors within the same marker body as it may clog the tip or alter the chemical stability of the ink.
Q: What is the shelf life of unused refills?
A: If kept sealed in their original packaging and stored in a cool, dry place, the refills have a shelf life of approximately 2 years.
Q: Will these refills fit standard highlighter bodies?
A: These are designed specifically for large head oil-based marker bodies, not standard water-based highlighters. Please check your pen model compatibility before purchasing.
Q: How do I install the refill?
A: Simply unscrew the bottom of your marker, remove the old cartridge, insert the new one with the felt tip facing outward, and screw the base back on tightly.
Q: Is the ink waterproof once it dries?
A: Yes, the oil-based formula is water-resistant and smear-proof once fully dried, making it suitable for outdoor or industrial use.
