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

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.

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.

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.

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

My only concern was if the refill would work in my pen and it fit perfectly. I have had bad experiences with other refills.

These work, they last, and they write well. Better than any Parker Pen refills that I've purchased over the last 1.5 years. Over the last couple years the Parker Pen refills have gone downhill. Most recently I purchased 2 of them and each ran out of ink after filling a mere 1.5 notebook pages. Needless to say, this turn of quality has left me frustrated and ready to chuck my fancy pens (which I am dedicated to!) for Bics, which seem to at least write on request. Enter these quality refills. Much cheaper than the Parker refills and so far they have outlasted them. They also perform well with a lovely, smooth glide with ample ink on the page. Finally a solution to the horrible Parker refills. I'm going to stock up, just in case.

These refills are absolutely worth it. I have ordered a pack that has lasted almost 2 years. I'm down to my last few and will absolutely order these again. I'm not a pen snob or anything like that but I do appreciate when things work well. This does that and more. No issues at all. Will buy these again. I do write quite a bit with documentation and this has not failed. Highly recommend. These are going into a Parker Pen.

Replaced marginal cartridges that came in some tactical pens, they now write like a finer completive pen. Fuller and more consistent flow and line.
