Pilot, G2 Gel Ink Refills, Fine Point 0.7 mm, Black, Pack of 6

It's a great product. I always use these refills in my pens.

Great price. Ink flow and quality is good. I love the amount that are in the pack. They last a long time and the Dr. Grip pen I use them for is so comfortable and helps ease fatigue.

These work very well and last awhile.

I've owned a Waterman Phileas roller ball pen body for many years, and I loved the pen very much when I first bought it and started using it. But I have always found it very difficult to get a good refill cartridge for this pen. The Waterman roller ball refill cartridge is not that hard to find, but both my own experience with these refills as well as recent reviews from other consumers are hit and miss at best. Many recent purchasers of the Waterman refill report unacceptably poor performance, ranging from ink skipping to refills that just plain wouldn't write. My own luck with the Waterman refills was similar. As a result of these disappointing refill results, I went in search of a substitute refill, something not MADE for the Phileas, but usable in it.But as much as I love the Phileas roller ball body, finding a quality substitute refill that both fits properly (was not too long, not too short) and writes smoothly proved to be quite difficult. I searched on and off for years without ever finding a good substitute refill.It recently occurred to me to go browsing through blogs written by people who love their pens as much as I do, and it was there that I learned that many people had had good success using Pilot G2 Gel Ink Refills in their Phileas roller ball bodies. I ordered some, tried them out, and I am tremendously happy to report that A) the fit is perfect ... not too long (so it allows for complete screw-on closure of the front and back half of the body without forcing) and not too short (making for loose or incomplete engagement of the tip). It's JUST right! B) the ink flow and writing characteristics of the refill are wonderful, putting down a smooth line from the first stroke on the paper. At last! And don't overlook the pricing difference. For about $1 each, these refills are much more reasonably priced than any of the ones I've tried before that didn't work nearly as well.So, if you're a Waterman Phileas roller ball lover searching for a perfect replacement refill, I can HIGHLY recommend Pilot G2 Gel Ink Refill. Perfect fit, great, smooth line ... I'm totally satisfied.

Great pens and refills still available.

I am a big fan of these pens and their refills. In both my work as a writer, and now writing long hands notes when I study they have been a solid performer for me. I have three of the pens these go into and now have ordered two small packages of multiple refills. My problem is that out of the two boxes I have ordered it seems like one or two of the refills just don't want to keep a steady ink flow. I have hung them to the side of a monitor to allow them to flow down whenever they don't want to work. Today and yesterday I gave up and threw two of the refiles from the last box away. It is this an acceptable amount of waste on something I love using. I dont know but it would be nice if all of the refills worked properly all of the time.

My favorite pen writes again

I have been using the Pilot G2 pens for way over 20 years and love them. I have always purchased my gel ink refills at Walmart but they were out of stock for several weeks. Thought I would see if Amazon had them. Purchasing 12 (6 packs of 2 each) was the best deal but cheaper than Walmart. Amazon will be my go-to place for these refills from now on.
