I'm an artist, and sometimes draw with pens or pencils, so I'm very picky about them. This is a great refill for writing with. At least the point size I bought is, which is 1 mm, and is considered a broad point. I like the way it makes my writing look strong. I would be a good refill for drawing with, too, although you might want some different width points if you're going to draw. As advertised, this is a gel pen refill, which means the colors are strong. The black one is BLACK, not grey, and the blue one is a very dark blue, almost a blue-black. It looks good on stationery, and I would recommend it for someone with good bold handwriting. Most blue refills are a brilliant, royal blue, and they look cheap and junky to me. This dark blue is a rich, elegant color. It's also available in red, which is bright, but not TOO bright. I like the red to use when I'm proofreading copy because it's easy to see the marks because the red is bright, but also transparent enough that if you write over a printed or Xeroxed letter, you can still see the black underneath, which makes it easier to see what has to be fixed. When you first start writing with the refill, it's VERY juicy. Eventually, this excess ink (which I, personally, like) eases off. Unless you're almost out of ink, though, this refill lays down a wet, strong mark, and will smear if you rub it without letting it dry. It's a writing experience that's very similar to using a fountain pen, but the point is a bit more sturdy. The ink tends to sink into the paper, too, so it's a good choice for writing checks and signing legal documents. This is without a doubt, my favorite pen refill! Oh, I bought this at Amazon, and I thought the shipping was exorbitant, but then I was surprised that the refills arrived almost instantly! If you're in a rush, this might be the best way to go. I'd like the option of cheaper shipping and waiting for it though. If I'd ordered one package of refills, the shipping would have cost more than the refills!

The Uniball Signo 207 Impact RT Retractable Gel Pen is awesome! It fits perfectly in my pen holder and writes like a dream. The gel ink flows smoothly, making my writing experience so much more enjoyable. I love the retractable feature, too—it’s super convenient for quick notes. If you’re looking for a reliable gel pen that combines comfort and style, this one is definitely a winner! Highly recommend!

I go through many, many pens by writing in a lab notebook everyday. For years, I've been sticking with these Uni-ball gel pens. First and foremost, the quality of the ink is excellent. After it dries (not so long as people claim–less than 5 minutes, usually), the ink is very resistant to any sort of solvent, because it is pigment-based. That is, the ink is not a dye, but is tiny black particulates suspended in a gel. I've actually put the ink through the test with chloroform, methanol, acetonitrile, DMSO, water, and a few other solvents. The pens themselves are very comfortable in my hand, and the redesigned rubber grip seems like an improvement. Another selling point, for me, was the ability to refill ink cartridges. Downside: The ink does not last long at all. I go through refill cartridges very fast. And not only are they not carried in most grocery or office-supply store, but the refill prices for most vendors online is more than buying new pens, which kind of defeats the purpose of getting refills. However, I did find a good deal through the Amazon add-on program: $0.99 per refill 2-pack instead of $3-5 as usual. But I didn't find that deal when I searched for the refills, so it was really more luck that enabled me to find this item (at this price) at all. So I bought 20 refill packs at once.

I like this pen cartridge. Ithe ink is indelible.

These refills worked for my purposes. Uni-ball has more than one refill. Some refills (like this one) have a longer plastic section between the metal tip and the ink tube. These tend to go into "click" pens. The plastic section was white. Others have a shorter section with a flared lip. That type goes into "stick" pens. Those had a green section. This refill shows the longer white plastic section (the type I wanted). The package I received had a green section. At first I was disappointed b/c I thought I had ordered the wrong thing, then I compared them to the other green tipped refills I had. While the plastic section is green instead of white, it is long and has not lip (like the white type). It looks like maybe Uni-ball may no longer be using the white/green tip to differentiate between click/stick pens and maybe all the tips are green now. Who know? This same refill at the depot of office supplies local to my house still has the white tips (but only in blue and in the thinner ink tip so I ordered them here). I'm happy with the refill. I mentioned the color thing in case anyone else runs into this situation and might find it helpful.

Replace the ink cartridge saves $$ and while keeping the same comfort and quality .

Usually, I don't like to write in liquid ink or gel pens because they smear very easily, but one of the things I like about the Uni-Ball Signo 207 pens and the ink refills is that it dries much faster than other brands and the chances of it smearing are much slimmer. The color is also very bold, which makes it easier to read and has a special ink to prevent check/document fraud. I would recommend this to people who write a lot of checks, or just want a ink refill that makes it easy write smoothly and quickly.

So thankful for finding this replacement ink will never have to throw away my pens.

Los recambios son más pequeños, por lo tanto no sirven. La calidad no la puedo juzgar. Veré a ver si me dan una solución.

con il refill da pochi centesimi si risparmiano 4 euro di penna nuova!

quick delivery and works perfect

The refills did not fit my original Uniball pen case! I would NOT recommend these as they are totally unsuitable as refills and I can't use them.

While I wanted Bold, this turned out to be too bold. Not sure if I just got a bad batch, but mine have displayed a propensity to bleed ink from the north end if left stored in the pen horizontally. The resulting mess gives substance to your trash bin being the new recipient of not only the refill, but the pen as well.
