Parker Compatible Gel Ink Ballpoint Refills 12 Pack,0.7mm Medium Point-Black, Smooth Writing Replaceable German Ink Tactical Pen Refills for Parker Ballpoint/UZI Pen

Very nice refills. Ink flows good, no smearing. Great value for the quality.

This is a very good quality refill. It is a perfect fit in my Parker pen. The ink is very bright and flows well with no effort.. I like them so much that I put them in other brands of pen where they fit. Very pleased.

Overall I am pleased. I have a favorite pen for work and have used ballpoint refills for years. Recently we approved the use of gel pens (because our office supplier cannot get ballpoint pens right now lol) so I ordered these straight away. They arrived with 3 of the refills having lost the protective cap and had leaked slightly. I used one of those first and they write smooth and have not leaked any further. The ball leaves a smooth skip free line, and the gel ink is just a joy to write with (terminus me of a smooth fountain pen). These fit my brass pen perfectly and I have not had any other issues. I do worry about the other 2 leakers drying out before I can use them, but we shall see.

I recently bought a couple of the Bolt Action tactical pens (which are AWESOME!); which are serious pieces of solid brass or titanium, I bought one of each. But the ink cartridges that came inside them were fine points and kind of "scratchy" feeling when you wrote with them. I use these pens every day, so not only can the pens give a bad guy a good poke, I also need them to write well. After trying a couple of other refills (in my humble opinion) these Unibene Gels are the perfect cartridge. Hands down. They come with a wax ball on the tips to make sure that the ink stays fresh AND also a rubber tip OVER the wax! Great presentation. I like a medium to bold point, and the Unibene medium is perfect. The ink just glides on the paper, smooth, and it actually makes my handwriting look better than any plain ballpoint (especially since I write in cursive). These are the refills that I am going to use from now on. Oh, and they're made especially for tactical pens! They're very stout. I had to open the end of the pen just a tad to accommodate these oversize tips. Now my pen is not only a serious spike (and I love to fiddle with the bolt.. calming) but it writes beautifully (glides is a more accurate description!

These ballpoint pen refills are a great value and so far I am very pleased with the quality and utility. I like the way they write and the fact that the refills are available with gel ink.

Used for a couple of months now. The first one dried up in two weeks and the second one just blew up in my shirt pocket and destroyed a $60 polo shirt halfway through my day on a business trip. I’ll be throwing the rest out as soon as I get home. Thanks for nothing.

I had three refills (two blue, one black) that died and became scratchy within a few lines. I have one black one that is currently working fine. I've had duds from the larger brands that were probably old stock (they were brown D1 refills -so not popular). what is unfortunate is the ones that aren't working will give you hope for about three or four letters, then will die off. I'm not sure what the deal is with these non-working ones. These fit in my Retro 51 (early 2000s non-Tornando twish pen) and Rotring R 600.

I needed a refill for a very nice Newhall Street pen I have. They are out of business, but this refill cartridge fits perfectly. I expect many more years of use from this pen now.

Very smooth and writes perfectly. Color is great
