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.

Very good replacement for Parker pens

These rollerball refills are okay and work for what I need them for. The blue ink writes smoothly enough and they fit my Parker-compatible pen as expected. They’re not the best refills I’ve used, but for everyday writing and having extras on hand, they get the job done. Overall, a decent option for the price.

These refills are scratchy, require a lot of pressure to write, and had less consistent flow than the dying Quink refills I bought them to replace. I tested all six and none worked well. I can't speak of the longevity because I had to throw the entire pack in the garbage. They make the infamous $0.30 Bic Cristal pens feel like a luxury item in comparison. Worse than nothing. Absolutely do not buy.

Writes very well

The tip doesn’t roll smoothly. It works just fine if pressing hard and forcing ink out. Gentle pressure you can feel how much friction there really is and the ink doesn’t come out as smooth as the official product. Pro - inexpensive Con - ink doesn’t flow out smoothly under low pressure Overall Spend money getting a new pen, something like a zebra or a pilot. Cost to experience, this refill comes out to being way more expensive in the long run.

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.
