Pilot Namiki IC100 Fountain Pen Ink Cartridges - Blue/Black (Pack of 2)

This is my go-to workhorse ink for work. I’ve used a wide range of fountain pen inks from brands like Montblanc, Iroshizuku, J. Herbin, Waterman, and Noodler’s, and I keep coming back to Pilot Blue Black. It hits a really nice sweet spot when it comes to flow, permanence, and ease of maintenance—three things that matter a lot when you’re writing regularly in a professional setting.The color itself is a deep, dark blue that maintains a classic, understated look while still offering just enough richness to give your writing some character. It’s not flashy or whimsical, which makes it ideal for office use—especially in more conservative or traditional environments where a bright or unusual ink color might come off as unprofessional.In short, Pilot Blue Black is a perfect ink for anyone who needs something reliable, legible, and appropriate for formal work documents or notes. It has presence without drawing too much attention, and it performs consistently across different nibs and paper types. If you're looking for a professional, no-nonsense ink that still has a bit of personality, this is the one.Photo- PBB has a nice sheen to it, on Tomoe RIver paper. Cheers!

No issues with leaking cartridges in my shipment. Similar cost to buying a refill bottles. Easy install for my Pilot Prera.

fast shipping, packaged well.

Been using this ink for my fountain pen ink journal with, excellent product and in many colors.Excellent SellerThankyou

Pilot makes excellent products and I would give this 5 star review if it were just Pilot and the refills. But I received my refills in their boxes inside a plastic bag. Both boxes of refills had been damaged with one or two refills in each box busted and leaking into the box. Fortunately, the spilled ink had dried by the time I opened the plastic package.Otherwise, Pilot would get 10 stars if I could give them that many. The shipping/packaging or maybe the storage was at fault here.Plus the seller should update the pictures of the refill boxes. They are now blue with white writing.

Great inks

These work well although they don’t last long if you write a bit!

its Pilot ink, writes well and dries fast, I really like this blue/black color not glaring blue but just a nice gentle easy to read color.
