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

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

Excellent replacement refills

I treat these refills like slim pens in their own right. They fit nicely where bigger pens don't. The butt end cap isn't fixed, so I glue them. Then I can keep the cap on that end when I'm using the pen. Without the butt end cap, the front cap won't stay on the metal butt end, which is too bad—it would be even shorter then.

Had hoped these would be acceptable in a Parker rollerball pen. Wrong. The mechanical fit is OK. The writing is terrible - not smooth, skips (as if insufficient ink), and refuses to write on many types of treated paper surfaces that an ordinary pen writes on easily. Tried more than one, some variation, but not success. Used one for an extended amount of scribbling, hoping that it would get better - no. Definitely not "Parker quality".

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 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!

★★★☆☆ (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.

Meets expectations

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
