The ink turns darker...

The ink turns darker with increased use, so don't despair if the color looks too light initially. Appears more like a dark blue than dark gray ( like the lamy blue-black cartridge). The shade is darker with the fine point nibs. Easy on the eyes against yellowish tinged paper.

I use the pilot fountain pen for taking notes and at first i found the ink to be too light. But then upon extended use, the ink turns darker--i dunno if it's the pen or the ink, but it is great! I like this better than the black.

Not really what I'd call blue-black, more like a weak bluey-grey. I was hoping for a much bolder colour, similar to the Pilot/Namiki black with a little blue shading. Unfortunately, I couldn't find a decent review for this specific shade prior to trying it.

The ink seems to transfer itself to the paper in all the right ways, with no particular penchant for feathering, bleed through, drying out or any other bad habits. Maybe it helps to only be used with Pilot nibs, an obvious benefit of proprietary cartridges.

However, I won't be buying these again as I'm just not a fan of the colour. Fortunately I've a number of Pilot pens around the house, so maybe I can get someone else to use the rest of these cartridges...

This blue black ink is good, but it seems lighter than other blue black inks and there is a subtle difference between the it and the blue ink

FYI - it is a bit lighter than I was expecting. I imagined more of a deep blue/black. Nevertheless, for the price I think it's great.

They work quite well and are a nice color. Not stark black, not too light. Easy to install and reliable.

Superb Ink, superb customer service, superb order processing, superb turnaround & delivery. I clearly think highly of JetPens; and, in this online world, where e-orders are so much more preferable to the old, familiar routine of traipsing through cluttered little stationery stores, and finding out what you came in for--a box of ink--a particular notebook--is not in stock, JetPens is that store where you walk in to their virtual space, and everything you want and need is in stock. Now how good does good get?
