Smooth and reliable
I have used many inks, but HERO remains a favorite. The non-carbon formula keeps my vintage pens clean and running well.

Perfect for daily journaling
The blue-black color is sophisticated and the quick-dry feature really works. No smudging on my left-handed writing anymore.

No more clogged pens
Switched to this non-clogging ink and haven't had to flush my pens in months. It's a game changer for maintenance.

Excellent black depth
The pure black model provides a deep, rich line that looks professional on high-quality paper. Highly recommended.

Great value for students
Bought this for my son's calligraphy practice. It flows smoothly without clogging the pen nib. The red color is vibrant.

Good flow, nice colors
The pure blue is a lovely shade, not too bright. Dries reasonably fast. Only wish the bottle was slightly larger.
Q: Does this come with a dropper or do I need to buy one separately?
A: The bottle comes with a built-in applicator brush under the cap for easy filling. A separate glass dropper is not included but can be purchased if preferred.
Q: Is the 'Quick-Dry Blue-Black' waterproof?
A: This ink is water-resistant once fully dried, meaning light exposure to water will not cause immediate smearing, but it is not fully waterproof for archival purposes.
Q: Is this ink safe to use in vintage fountain pens?
A: Yes, our non-carbon and non-clogging formula is specifically designed to be safe for both modern and vintage fountain pens, preventing sediment buildup.
Q: How long does it take for the blue-black ink to dry on standard notebook paper?
A: On standard 80gsm notebook paper, the quick-dry formula typically dries within 10 to 15 seconds, depending on the nib size and amount of ink laid down.
Q: Can I mix the red ink with the pure blue to make purple?
A: While physically possible, we do not recommend mixing different colors or batches as it may alter the chemical balance, potentially affecting flow and drying properties.
