Great value pack
Good quality ink that doesn't dry out quickly. I use these for my daily journaling. Only giving 4 stars because I wish they came in blue-black as well, but the black is solid.

No more clogging issues
My previous brand always seemed to clog if I didn't write for a few days. These Platinum cartridges keep flowing smoothly even after sitting idle for a week. Very impressed.

Good but runs out fast
The ink quality is excellent and writes very smoothly. However, since the cartridges are on the smaller side, I find myself changing them quite frequently if I write a lot.

Standard universal size
These are the standard European size cartridges. They work perfectly in my Lamy, Pilot, and TWSBI pens. The dye-based formula cleans up easily if you make a mess.

Perfect fit for my vintage pen
I was worried these wouldn't fit my older fountain pen, but they slid right in. The ink flow is consistent and the black is a nice deep shade. Highly recommend for anyone needing reliable refills.

Reliable Japanese quality
You can never go wrong with Platinum ink. It's water-resistant enough for notes but not permanent, which is exactly what I need. The packaging keeps them fresh until use.
Q: Can I use these in a converter instead of directly inserting the cartridge?
A: These are pre-filled disposable cartridges. If you wish to use a converter, you would need to purchase bottled ink rather than these cartridges, though some users carefully empty them to refill, which is not recommended.
Q: Will these cartridges fit a Lamy Safari fountain pen?
A: Yes, the Lamy Safari uses standard international short cartridges, and these Platinum INK-400 cartridges are compatible with that size.
Q: What is the expiration date on these cartridges?
A: When stored in a cool, dry place away from direct sunlight, these cartridges typically remain usable for several years. Specific batch dates are printed on the box packaging.
Q: How many milliliters of ink are in each cartridge?
A: Each individual cartridge contains approximately 0.9 ml of ink.
Q: Is this ink waterproof?
A: No, this is a dye-based ink designed for smooth writing and easy cleaning. It is not waterproof and may smear if exposed to water.
