Good flow, but fades slightly

The ink writes very well and hasn't clogged my pen once. However, I noticed the blue ink fades a bit more than premium brands after a few months in direct sunlight. Still good for internal documents.

Teacher approved!

I grade a lot of papers and go through ink quickly. This 50ml bottle lasts me a whole semester. The red is classic teacher red, and it never dries out in the bottle even after weeks of use.

Ideal for calligraphy practice

As a beginner in calligraphy, I needed an ink that wouldn't clog my nibs during long practice sessions. This non-carbon formula is perfect. The red shade is particularly striking for corrections and annotations.

Reliable and clean

Switched from cartridges to this bottled ink to save money. It's very clean and easy to fill. The only reason I didn't give 5 stars is that the bottle opening is a bit narrow for larger converters.

Great value, vibrant blue

The Pure Blue color is surprisingly vibrant and fun to write with. It's not waterproof, so be careful if you use a highlighter over it, but for the price, it's an excellent everyday ink.

Perfect for daily office writing

I bought the black ink for my daily journaling at work. It flows incredibly smoothly through my Hero pen without any skipping. The color is a deep, professional black that looks great on standard paper.

5 FAQ

Q: How long does the 50ml bottle typically last?

A: For average daily writing (approx. 2-3 pages), a 50ml bottle usually lasts between 2 to 4 months depending on the efficiency of your specific fountain pen's converter or piston mechanism.

Q: Is this ink safe to use in vintage fountain pens?

A: Yes, because this is a non-carbon, dye-based ink, it is generally safe for vintage pens as it is less likely to clog fine feed systems compared to carbon or iron-gall inks. However, always ensure your pen is clean before switching inks.

Q: Does the bottle come with a cleaning brush?

A: No, the 50ml bottle contains only the ink. Cleaning brushes or ultrasonic cleaners are sold separately in our accessories section.

Q: Is this ink waterproof?

A: No, this is a non-carbon dye ink, which means it is not waterproof. If exposed to water, the writing will smear or wash away. For archival purposes, please consider our pigment-based ink line.

Q: Can I mix the red and blue to make purple?

A: While physically possible, we do not recommend mixing different colors of fountain pen ink. Mixing can sometimes cause chemical reactions that lead to sedimentation or clogging within your pen.
