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

I literally NEVER write a review on a product, but had to on this one. FAR exceeded my expectations. I’m a bit of a pen freak and love smooth writing, comfortable feel, quality pens, and vibrant blue ink. The original Parker refills work great, don’t get me wrong, but the ink color is so dark on the new ones it’s almost black. For comparison, I love the Parker gel refills color as well as the Pentel Energel ones for their vibrancy and smooth writing (checks all my boxes). I was looking for a comparable rollerball refill for my Parker pen. This is it!! Unfortunately the medium point refills were out of stock (I’ll be ordering them immediately when their back), and I don’t typically use fine point but was willing to give it a try. It did not disappoint. These pictures show the fine point Unibene (0.5) compared to a Parker gel refill (0.7). The color is vibrant and smooth (bright royal blue if the pictures don’t show it well). In the picture, I’m writing on a thick ivory colored paper (but works great on bright white as well). Buy them if you’re like me. You’ll be glad you did! The ink dries quickly too which is an added bonus!

Much better than original Parker refills. Ink flow was amazing. Ink drying time was instant.

Very comparable to Parker-brand Fine point rollerball refills, and fit perfectly in my Parker IM rollerball pens. Based on an initial tryout, I think these Unibene refills produce a smoother and more saturated line than rollerball refills from Parker. Since I prefer extremely fine points, I was actually hoping that the Unibene refills with their prominent GEL marking would write more like a Uni-ball or Pentel gel refill with the same point size. However, Unibene must use a very wet gel ink (like the ink in Parker Jotter gel refills), because just like Parker gel refills, these 0.5 mm point Fine point Unibene rollerball refills produce virtually the same width line as a 0.7 mm Medium point Uni-Ball Signo or Pentel EnerGel refill. But if you like a wider line, then I think these Unibene refills are better than Parker refills, and certainly more economical.

I ordered these because I do not like the water based ink that comes in most "nicer" roller ball pens. I prefer the no-smear, quick dry, no-bleed characteristics that are common with gel ink pens (like the Pilot G-2). While these cartridges did fit my Parker roller ball pen nicely, the ink was much more bold than 0.5mm (i.e., the line was "fatter"), the ink bled through the paper worse than the original ink that came with the Parker pen (which was a water based ink) and the ink was not quick dry or no-smear as you would expect from a gel pen. I would not recommend these to anyone looking for a refill that performs like gel ink.

Worked well with parker pens

These fit perfectly and are much more economical that the parker original. They write perfectly and love the gel ink.

★★★☆☆ (3 out of 5 stars) I purchased the Unibene Parker Compatible Rollerball Refill (6 Pack) mainly because the price is fair for the quantity you receive. From a value standpoint, it meets expectations. However, ease of writing is not its strongest point. The ink flow is inconsistent at times, and the writing experience is not as smooth as I would expect from a rollerball refill. If you are looking for a consistently smooth, effortless line, this may be disappointing. For casual or occasional use, it is acceptable given the cost. That said, if writing comfort and smooth trace are important to you, I would recommend purchasing the original Parker refill or trying a different brand instead.

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.

So far so good on these refills. They fit my Parker roller ball pens perfectly and are working well.

Great value quick delovry perfect for my pen

Why buy new pens when refills fit the bill at a much much much cheaper price. I highly recommend this option to people who still know how to write cursive or can write at all
