Unibene Parker Compatible Rollerball Refill 12 Pack, 0.7mm Medium Point - Black & Blue, Smooth Writing Replaceable German Gel Ink Pen Refills for IM Sonnet Urban Pens

The refill fits the pen perfectly. And the writing quality is smooth, clear and leaves a very nice impression with no smear. I would purchase these refills again if/when I need them. Very happy with the product and the delivery time (one day!).

Always a little skeptical when getting off-brand refills as to whether they will actually fit and work. I'm glad to say that these work perfectly and fit my pens exactly. Very good value.

Good quality , good price , just what I was looking for.

I recently found a pen I used to love and decided to given a try, they work great I am so happy. No smudging very clear writing

I usually don't write reviews, but felt obligated to help prevent someone else's future frustration. With that said, I am unimpressed with the quality of these refills. They were cheaper than the Parker originals, and now I know why. When writing, no matter the media, type of paper, or tooth of the paper, the ink flow is inconsistent and spotty; often times having to go back and write over the lettering or press harder to get the ink to flow and be legible. Won't be buying these again.

Not that good, don't expect too much from the cheapest prices

These refills are perfect for Parker IM. I like this product. PS the only one thing... buy it as addition to something , so it would come in a box.... otherwise it got squished if it’s only one in bag.... 3 of 12 were damaged... and you cannot use those....

Better than actual Parker refills, but I wouldn’t compare this ink to “gel”. This is most certainly liquid ink. Gel ink would be usable on every type of paper with no bleeding or leafing.
