Unibene Parker Compatible Ballpoint Refills 12 Pack,1.0mm Medium Point-6 Black&6 Blue, Smooth Writing Replaceable German Ink Tactical Pen Refills for Parker Ballpoint/UZI Pen

These work perfectly in my favorite U-brands pens. The quality is great and the cost is very favorable for the current economic conditions. The set comes with 12 total refills (6 black/6 blue). The writing from the refill is very smooth so far. Don’t forget to keep the little spring from your current pen because they do not come with that since they are meant to replace multiple brands. Overall I am very pleased.

These pen refills worked great. The most important tip I can offer is to measure your existing pen cartridge (length and width) and select one that is the same shape and size, because there are many different varieties of refills. If this product is an exact replacement for what you already have, you will be happy with it.

I have a few pens that utilize Parker Style refills (and Fisher Space Pen and Rite in the Rain with included adapters) and have lately been looking for less expensive refill alternatives. I decided to order these because they were well rated, at a fair price, and the Germans tend to make good stuff. So far one or these refills has been installed in an Atomic Bear SWAT pen and was used for a couple of shifts at an outdoor job in January weather. The ink is of a good shade of blue, flows well, dries quickly and seems to be working well and as advertised. These refills are not pressurized and won’t write upside down or on damp paper like Rite in The Rain or Fisher Space Pens. However they are great for normal daily writing tasks in the office and/or on the job. Package arrived on time and in good condition, and I also like the price point on these. So far so good. I would recommend and do plan on purchasing again in the future.

Not bad at all for the price. I've had a few issues with the ink skipping...but not not much. The blue cartridges write nice and thick but the blacks seem a bit thinner. Haven't had smearing issues. Good refills for the money

Pleased with the quality & value.

Fit my pen perfectly and installed easily. And, I'm 88 years old with the use of one eye.

Good value, no gaps in writing. The blue feels a little smoother and lays down a little thicker, but some will prefer the more precise black. On re-order I had trouble making up my mind, but I went with the blue for the feel and color.

I have only used one so far but it works great. Nice and smooth.

Long- life refills.

I was searching for gel-ink refills These snuck in - they are ordinary ballpoint ink good enough for what they, but not what I wanted. Now we have to spend time reading the fine print!
