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

My new favorite refill and I use them in my retro51 torpedo pens. Solid stream, smooth and fits perfectly in these Torpedo pens. Unibene on top in photo, jetstream refill, the bottom scribble in the photo.

Very happy with these aftermarket Parker rollerball refills. They have never leaked and they seem to last as long as the original Parker brand refills. Parker rollerball refills sell, typically, for around $4.00 a piece, and these end up at around 75cents each, with purchase of qty 12. . I will check if this company, Unibene, also produces refills for my Cartier, Lamy and Waterman pens. Thanks for a very good and extremely price competitive product!!

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.

Nice dark black ink. Writes very smoothly. good value. Will buy again when needed.

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!

Very poor writing quality. 0 rating, but not an option. . A pack of 12 X 0= still 0. I saved nothing. Spend more and get quality Parker brand

Some of these work well but some just don’t write well. Almost like they have grease on the tip. Hard to know what you are getting when yiu put a new refill in.

These are great!! I only like buying the Parker brand refills so this is out of the norm, because I did buy non Parker rollerball refills & they didn’t work out very well, but these function very well. I love the blue color, they dry quickly, they are of good quality, & Good value for money. I recommend them .

Very smooth and writes perfectly. Color is great

Top level product But don't store for a long time

They do the job and they don't leak, which was a problem in tactical pens that don't write much.

Estou muito satisfeito.

not smooth to write with
