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

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.

Excellent replacement

I tried to save some money and buy these non-Parker refills. I used several of them and they were all terrible. The ink flows intermittently and parts of letters just don't appear so you need to write over them again which looks bad and is frustrating. Don't cheap out like I did and buy the real ones. I've since bought the real ones from Parker and they work beautifully.

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.

Writes very well

As much as I want to love this ink refill, I have a major problem with it. Fresh out of the box, the ink refills skip. And it's a multitude of them that have this problem. The color of the ink itself is really good, and it allows my Parker IM to glide with ease across the page. Plus, the price is way better than Parker's proprietary refills. Because the skip rate is such a major issue, I had to dock 3 stars. It can ruin your rhythm of writing and can be such a great inconvenience.

Smooth writing with no smear. Fit all of my roller pens that use the Parker refill style. I ordered 2 packs and am very happy with my purchases.

I love the quality of the ink. Quick dry and initially no skipping or overflow. After three weeks, the refill seems does not seem to write and strong and appears that it may be running out of ink. Still matched the quality of the original refill and a great value.

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

المنتج رائع جدااااااااا أفضل من العبوات السابقة بكثير

An effective replacement for my Parker rollerball pens. Like the blue colour ink. Writes smooth and with lines thicker than Parker.

If you're usually using the brand name refill this substitute will make you cringe. The roller tip is no where near as smooth as the original and the blue ink appears watered down compared to the genuine refill.
