Pilot Namiki IC100 Fountain Pen Ink Cartridges, Black, 12-Pack

Works with other fountain pens. Easy to use, good quality ink.

Great product. Ink flows beautifully and drys quickly. As a left handed person, I can attest to no issues with smearing.

The ink feels quite nice!

Got these to use with my pilot Kaküno pen and they work great. Quality is pretty good though if you use them for more than writing the ink will run out fast. Depending on the paper it can bleed through a bit, but overall really worth the cost

These seem fine as replacement catridges, but you should consider a nicer design anyway imo.

I bought these for my Pilot Cocoon, and my daughter's Pilot Metropolitan pens. I didn't buy them for the ink, I bought them to store different colors to test in our pens. My daughter and I love our Pilot Metropolitans and Pilot Cocoons (basically a Japanese market Metropolitan). The smaller size, though, means that ink capacity is limited. This is especially true if you like to use an ink fill converter such as a piston operated or squeeze type. The best way to get maximum capacity from the smaller pen is to use ink cartridges. The beauty of this is that cartridges can be reused by rinsing them out and refilling them with a syringe. The cartridges can even be filled and stored for later use. The way to do this is to squeeze the cartridge allowing the little round "cap" to fall out, and then re-seating the cap after refilling the cartridge. There are good demonstrations of this online if you google "reusing fountain pen ink cartridges" or the like. Anyway, if you want maximum capacity out of your smaller metropolitan or cocoon, cartridges are the way to go - inexpensive and ultra versatile.

The Pilot Namiki ink cartridges are a perfect match for the Pilot Kalinin fountain pen. They fit securely, install easily, and deliver a smooth, consistent ink flow right from the first stroke. No skipping, no hard starts—just clean, reliable writing every time. The ink quality is excellent. The black and blue-black colors are rich and sharp, with good dry time and minimal feathering, even on regular paper. They’re also low-maintenance—great for everyday writing or quick note-taking without worrying about cleaning converters or dealing with bottled ink. These cartridges are proprietary, so they only work with Pilot or Namiki pens—but for Kalinin users, that’s not a downside. They’re super convenient, portable, and leak-free, making them ideal for students, professionals, or anyone on the go. While they don’t offer the capacity of a converter or the color range of bottled ink, they make up for it with ease of use and reliability. If you’re using the Kalinin and want a clean, mess-free refill option, these cartridges are a no-brainer. Highly recommended for any Pilot fountain pen user looking for simplicity and performance in one.

Works like a charm if you institute correctly. Good by for 12 cartridges. Arrived intact. Good black depth. Highly recommended.

Great for my pilot Cocoon (Japanese version of the MR that takes standard cartridges)

La uso para una pluma de la misma marca y muy bien
