UnibeneParker Compatible Rollerball Refill 6 Pack, 0.7mm Medium Point - Blue, Smooth Writing Replaceable German Gel Ink Pen Refills for IM Sonnet Urban Pens

These refills are amazing I’ll be buying more

While I have always been a Parker Fan with several Rollerballs and a Fountain pen, I was disappointed with the cartridge in my new Parker Jotter. It was much finer that I would have expected from a medium tip. Not to mention, under certain conditions it was "skipping".I am very happy with the Unibene replacement. It is as full and consistent as I would have expected. I also like their blue ink color. Will need to see how longevity plays out. However the Unibene replacement cartridges I have used in some tactical pens have been a pleasant surprise, thus the new loyalty to this brand.I believe its worth a try for this modest investment.

I bought these for Retro 1951 pen. They do not fit. Returning them. I guess I didn't do enough research. My understanding was the Retro 1951 took a Parker style refill but it does not. If the pen was not a gift, and I used rollerball style pens I would keep these. They seem decent quality.

If you own and use ANY Parker rollerball pen (from the Vector to the Duofold Centennial), then your pens NEED this refill! They are MUCH better than the Parker or Monteverde refills! They are smooth, lay down a beautiful skip-free line, and they LAST! What a value! Parker could learn a thing or two by studying this refill! The ink dries fairly quickly which leaves your page smudge free! I got the black refills, and the lines are nice and dark! I use them in ALL of my Parker rollerball pens. The pen shown in the pics is the Parker Premier rollerball in black with gold trims. These refills are especially nice in this pen, and make it an absolute pleasure to write with! If you're looking for an upgrade to the "skippy" Parker branded refills, look no further! Unibene has you covered! Highly recommend!

I am discarding most of the refills from this package because the ink flow is so unreliable. The point of using a rollerball is to enjoy a smooth, consistent flow of ink without needing to apply as much pressure as with a ballpoint. These Unibene refills are blotchy and scratchy. I discovered this too late to return the product. The first refill worked okay but never as well as the Parker; the next two out of the package were useless; and I'm putting up with #4 for the next day or two, until my new Parker brand refills arrive. This lower price of this aftermarket product is false economy. Stick with the original.

Refills were shipped quickly and they fit my pen perfectly.The rollerball on these is fantastic! Ink color is consistent every time. The amount of ink that hits the paper is perfect. Ink dries fast (no smudges).Like most people these days, my information capture and signatures are digital. However, I noticed there are times when one needs to use a pen e.g when business need signatures on paper. During the pandemic, I've had to use those disposable pens from the "clean jar" when signatures-on-paper were required. After doing that a few times I decided to dig up my trusty Parker pen and press it into duty. I ordered these refills via Amazon so I could get started as soon as possible.I was surprised how much I enjoyed the sensation of pen on paper (and using my own pen). Now I find myself using the pen more and more. A simple pleasure.

I wouldn’t mind if these refills lasted a bit longer than they currently do for me. They seem to run out quickly, and I don't even use them in my main writing pen, so it's not like they get a lot of use every time I write. However, when they are newly installed, they deliver great quality.

I had a difficult time finding these refills in the local office supplies stores. Now, I know I can re-order them through Amazon. Also, the refills came early!
