Smooth writing experience

The ink flow is consistent from start to finish. I use these for daily journaling and haven't had any issues with drying out or blobbing.

Good but limited color variety

The quality is decent, but I wished there were more varied colors in the 'colored' assortment. Mostly just standard blues and blacks.

Great value for the price

You get a good mix of colors in the pack. The black is very dark and rich. Only giving 4 stars because one cartridge arrived slightly cracked, but the rest were fine.

Excellent for travel

These are so convenient to throw in my bag. No mess like bottled ink. The non-carbon formula seems to clean out easily when I switch colors.

Perfect fit for my vintage pen

I was worried these wouldn't fit my older fountain pen, but the 34mm cartridges slid in perfectly. The blue ink flows smoothly without skipping.

Reliable universal cartridges

Works with both my student pens and my higher-end models. The 26mm size is great for smaller barrels. Highly recommend for beginners.

5 FAQ

Q: Do these cartridges work with Lamy Safari pens?

A: Yes, the Lamy Safari typically uses the Z24 converter or specific Lamy cartridges, but many users find the 34mm Hongdian cartridges fit securely. We recommend checking your specific pen model's caliber requirement.

Q: Are these cartridges refillable?

A: No, these are designed as disposable single-use capsules. Once empty, they should be recycled or discarded properly.

Q: How long does one cartridge last on average?

A: Usage varies by pen nib size and writing style, but a standard cartridge typically lasts between 3 to 7 days of regular daily writing.

Q: Is the ink waterproof?

A: No, these are water-based non-carbon inks designed for smooth writing and easy cleaning. They are not waterproof and may smear if exposed to water.

Q: Can I mix different colors in the same pen?

A: While physically possible, we strongly advise flushing the pen with water between color changes to prevent muddying the ink or clogging the feed.
