Unibene Parker Compatible Gel Ink Ballpoint Refills 12 Pack,0.7mm Medium Point- 6 Black&6 Blue, Smooth Writing Replaceable German Ink Tactical Pen Refills for Parker Ballpoint/UZI Pen

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!!

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

These have been working fine though are not the highest quality for my Retro Tornado. You will need a spring though. However, when using these in my Kaweco Sport, they have been drying out / not working fairly fast, though I am in cold winter weather so that could potentially be a factor.

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!

great pens for my pen collection.

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.

I love these. They write so smooth -- better than the original.
