Unibene 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

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.

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.

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.

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!!

In my opinion, they write better than the one that came with the pen.

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

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.

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

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
