Smooth writing experience
The ink color is a lovely deep blue-black. It dries reasonably fast on standard paper without feathering.

Perfect fit for my Pilot 78G
These cartridges slide in effortlessly and the ink flow is incredibly smooth. No skipping or hard starts even after leaving the pen capped for a few days.

Genuine quality
Always buy genuine cartridges for expensive pens. These work perfectly with my V7 converter setup as well.

Great value pack
Good quality ink that writes cleanly. I deducted one star only because I wish they offered a bulk pack of 12 instead of just 6.

No more clogging!
I switched from a generic brand to these genuine Pilot cartridges and the difference is night and day. My pen hasn't clogged once since switching.

Ideal for travel
I keep a few of these in my laptop bag for my Pilot Smile. They are small, lightweight, and never leak in my pocket.
Q: What is the shelf life of these cartridges?
A: If stored in a cool, dry place away from direct sunlight, these cartridges typically remain usable for up to 5 years from the manufacturing date printed on the box.
Q: Is the ink waterproof?
A: No, these IC-50 cartridges contain dye-based ink which is not waterproof. If you need water resistance, we recommend looking into our pigment ink options.
Q: Are these cartridges compatible with the Pilot Metropolitan pen?
A: No, the Pilot Metropolitan typically uses the larger IC-100 cartridges. The IC-50 are designed for smaller nib units like those in the 78G, 88G, and Smile models.
Q: Can I use these in a Pilot V5 RT refillable pen?
A: Yes, the V5 RT (Refillable Technology) model is specifically designed to accept standard Pilot ink cartridges like the IC-50 once the original factory refill is removed.
Q: How many pages can one cartridge write?
A: While it varies based on writing style and nib size, a single IC-50 cartridge generally lasts for approximately 10 to 15 pages of continuous writing with a medium nib.
