Perfect for my child's school supplies
These cartridges fit my son's fountain pen perfectly. The blue-black color is exactly what his teacher requested, and the price for a bulk pack is unbeatable.

Solid everyday cartridges
Nothing fancy, just reliable ink for everyday writing. The pure blue is a lovely shade. Would recommend for students.

Universal fit as advertised
I was worried these wouldn't fit my vintage pen, but the 3.4mm caliber is truly universal. The red ink is vibrant and great for grading papers.

Decent ink, some leakage issues
The ink color is nice, but I found two cartridges in the box that had leaked slightly inside the plastic wrap. The rest worked fine though.

Great for bulk buying
As a teacher, I go through a lot of ink. This factory direct option saves me so much money compared to brand names, and the quality is surprisingly good.

Good value, smooth flow
I bought the black ink for my daily journaling. The flow is consistent and doesn't skip. One star off because the packaging was slightly crushed on arrival, but the cartridges themselves were fine.
Q: Can I use these in a converter instead of directly inserting them?
A: These are pre-filled disposable cartridges. If you wish to use a converter, you would need to purchase bottled ink instead, as these cartridges cannot be refilled.
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: Do these cartridges fit Lamy Safari pens?
A: Yes, Lamy Safari pens use the standard 3.4mm international cartridge size, so these will fit perfectly.
Q: What is the expiration date on these cartridges?
A: Our cartridges have a shelf life of 3 years. We ship fresh stock, and the manufacturing date is printed on the bottom of the box.
Q: How many cartridges are included in one order?
A: Each order includes a box of 50 cartridges. You can select your preferred color mix or single color during checkout.
