Perfect for my daughter's school supplies
These cartridges fit perfectly into her beginner fountain pen. The colors are vibrant, especially the blue, and they don't leak in her backpack. Great value for the price.

No more mess!
Switching from bottled ink to these cartridges has saved me so much cleanup time. They are easy to swap out, and the seal keeps them fresh until I need them.

Excellent bulk pack
Buying in bulk is much cheaper than buying small packs at the stationery store. The quality is consistent across all three colors. Highly recommend for teachers.

Good universal fit
I was worried these wouldn't fit my vintage pen, but the 3.4mm size worked flawlessly. The black ink flows smoothly. Only giving 4 stars because the red is slightly lighter than expected.

Great for travel
I keep a few of these in my laptop bag for meetings. They are lightweight, durable, and the caps stay secure. The pure blue is my favorite shade.

Decent but runs out quickly
The ink quality is fine for everyday writing, but I feel like I go through them faster than branded cartridges. Still, for the price, it's a fair trade-off.
Q: Can I mix colors in the same pen?
A: We recommend flushing the pen with water before switching colors to prevent mixing and potential clogging. While you can switch them, mixing inside the feed is not advised.
Q: Are these cartridges refillable?
A: No, these are designed as single-use disposable cartridges. For reusable options, please check our section on ink converters.
Q: Will these fit a Lamy Safari fountain pen?
A: Yes, the Lamy Safari uses standard European 3.4mm cartridges, so these will fit perfectly.
Q: Is the ink waterproof?
A: No, this is water-based dye ink designed for smooth writing and easy cleaning. It is not waterproof and may smear if exposed to water.
Q: How long do the cartridges last once opened?
A: Once inserted into a pen, a single cartridge typically lasts for 2-3 weeks of daily writing, depending on your writing style and nib size.
