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!

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

Great inks

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.

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

Good price for a pack of two. The design of the box is different from the one in the description, but the cartridges are the same. These should last for a while. The color is very juicy dark blue. Initially, I thought there were two types in each box: blue and black. I didn't read the listing thoroughly and the header is a little confusing. Other than that it is all good.

fast shipping, packaged well.

These are a staple for my fountain pen collection. I love the color because it is not fully black, but a very very dark blue, giving a unique hue. These are so simple to use, just popping in and out if I do not feel like using the ink converter. The do tend to run out rather quickly depending on the nib size you use and without showing signs they are getting low, recommend having a backup with you.
