Unibene Gel Ink Rollerball Refills 12 Pack, 0.5mm Fine Point - Blue, Standard Rolling Ball Refills Fit Most Ordinary Rollerball Pen, Waterman Pilot Pentel Compatible Cartridges

I have lots of left over promotional roller ball pens from when I travelled in sales. The problem is, the refils in them NEVER worked well, even new. They were freebies so I didn't expect more. Several of the pens are really nice so I tried these. They fit perfectly and write ALL the time. I wish I'd found them sooner. Highly recommended and I would buy again if I ever manage to use up the ones i have!

I was afraid that it wouldn't fit my pen. But after comparing the old ink cartridge with this brand, I decided to take a chance. It fits perfectly! It's not quite as smooth writing as the old ink cartridge, but it works and the fine tip is just the ticket. For the price point, I can't complain.

I've used 3 of these so far, out of a pack of 12. The performance has been consistent between all three. The gel ink flows well and has a nice consistency and color. The down side is the rollerball tip, at least in the "fine" size that I tried. It's very scratchy and rough, and that's been true with all 3 that I've used. Noticeably more so than other fine rollerball refills I've tried (e.g., Schmidt, Waterman, Pilot, etc.). Overall, however, I think these refills are still a very good value for the price.

These did not fit my Cross Rollerball pen, but did fit another pen I had. They write on. Don’t write as smoothly or quite as well as the true Cross gel rollerball refills. They are priced for great value.

They will not work in my pen. The refills are not threaded as shown in the photo on Amazon. I am trying to figure out how to return them now. Very disappointed. Instead of being threaded, they have a triangular configuration that do not fit the Meisterstuck. If you look at the photo on Amazon, it clearly shows the cartridges advertised as being threaded to fit the Meisterstuck. Very disappointed. Do you offer a refill for the Meisterstuck and how do I return these for a refund or for refills to fit my pen? I had to order original Mont Blanc refills from Amazon. Please advise. Thanks, Curtis Cox.

We had some fine quality pens given to us but they came with extra fine point rollerball nibs that we did not like. I found this online and ordered these to replace the ones that came with the pens. These are excellent, they fit perfectly, they arrived on time and they write very well.

WAS GLAD TO SEE THESE REFILLS FIT MY PENS TO A TEE. I HAVE SEVERAL MICRO CERAMIC PENS THAT I HAVE NOT BEEN ABLE TO USE FOR YEARS. THEY WHERE MY FAVORITE.. THE PRICE WAS GREAT. SMOOTH WRITING TIPS.WAS GLAD I COULD GET BOTH THE BLACK, AND BLUE AND ALSO AVAILABLE IN A MIX PACKAGE OF BOTH. I USED THE .5/FINE TIPS THE LENGTH OF THE REFILLS WAS ALSO PERFECT FOR THE PEN SIZE. GLAD I WAS ALBE TO FIND THESE THOUGH THROUGH AMAZON.

I was given a waterman pen for my birthday and loved the pen. What I didn't like the cost for refills which didn't work with generic ink I previously used with my other ball point pen. I did some research and based on reviews, this came up. I've replaced my pen with this ink and it writes as good as the original for a fraction of the cost of authentic ones. I recommend if you have a waterman pen and need blue/black replacement ink. So fat so good.
