Pilot Namiki IC100 Fountain Pen Ink Cartridge, Black, 12 Cartridges per Pack (Pack of 2)

Flows well. Dries quickly. No leaking

I was using this to replace the refillable cartridge in my pen. I usually clean pens well in between cartridges, and I did that when I swapped out the refillable. It took quite a while to get the ink to come back down, but now that it has it's working very well and the writing looks great.

Ink cartridges are easy to use and the ink flow is perfect. Value is excellent and the cartridges last long even with heavy use. I will buy again.

It’s very easy to use fountain pen with these cartridges. They are consistent in quality. Will purchase again.

The ink worked amazing.

I use these in my Vanishing Point pen. They work great. Very easy to remove the old cartridge and put the new one in. Sometimes it takes a while for the ink to start flowing again, but it eventually does and then works just fine. I would say that this ink dries almost immediately. I’ve used it on cheap copy paper and quality paper (TRP; Stalogy) and it performs decently on both. It’s not waterproof so be mindful that it can smear if wet. I did refill a cartridge I cleaned out and put one of my bottled inks in it, but I ultimately prefer the convenience of the cartridge in my VP. I still save my cartridges so I can use my bottled inks in another Pilot fountain pen that’s also compatible with these cartridges. One more thing: the inks in these tend to dry light. I have Blue-Black and it looks more straight up blue. I also have Sepia and it looks like a washed out reddish brown color. The black tends to be dark when you start writing then becomes lighter as you go. Not sure if this is the case with everyone, but I thought it worth mentioning. I’m not sure why other reviewers say they don’t get a lot of writing with these pens. I write daily with it and a cartridge usually lasts me about 3 weeks, which considering the size of the cartridge, I’d say that’s a very generous amount. 0Recommended.

Found it to be a fantastic ink for my Pilot MR fountain pen, that I will buy more. The price I found is less than other sellers. Good price and good ink.

Easy to install. Ink is great and package is small and doesn't take up too much space

Super quality ink that flows well and helps reduce writing strain. The only product I use with my Namiki Retractable Fountain Pen. Highly recommended

Long time to get delivery and prices have gone up considerably. Less expensive and just as good quality fountain pens that do not require these refills

Useful for all pilot fountain pens. I am using it in vanishing point.

The way its posted you'd think you're getting 24 cartridges of IC-100 Black. That's not it. You get 2 packs with 6 cartridges of IC-50 Black. So you only get 12. It's a rip off
