Unibene Parker Compatible Gel Ink Ballpoint Refills 12 Pack,0.7mm Medium Point-Black, Smooth Writing Replaceable German Ink Tactical Pen Refills for Parker Ballpoint/UZI Pen

This is a very good quality refill. It is a perfect fit in my Parker pen. The ink is very bright and flows well with no effort.. I like them so much that I put them in other brands of pen where they fit. Very pleased.

These ballpoint pen refills are a great value and so far I am very pleased with the quality and utility. I like the way they write and the fact that the refills are available with gel ink.

These have been working fine though are not the highest quality for my Retro Tornado. You will need a spring though. However, when using these in my Kaweco Sport, they have been drying out / not working fairly fast, though I am in cold winter weather so that could potentially be a factor.

Great cartridge with a smooth ink flow, and lots of spares. These will last me a while for sure!

I recently bought a couple of the Bolt Action tactical pens (which are AWESOME!); which are serious pieces of solid brass or titanium, I bought one of each. But the ink cartridges that came inside them were fine points and kind of "scratchy" feeling when you wrote with them. I use these pens every day, so not only can the pens give a bad guy a good poke, I also need them to write well. After trying a couple of other refills (in my humble opinion) these Unibene Gels are the perfect cartridge. Hands down. They come with a wax ball on the tips to make sure that the ink stays fresh AND also a rubber tip OVER the wax! Great presentation. I like a medium to bold point, and the Unibene medium is perfect. The ink just glides on the paper, smooth, and it actually makes my handwriting look better than any plain ballpoint (especially since I write in cursive). These are the refills that I am going to use from now on. Oh, and they're made especially for tactical pens! They're very stout. I had to open the end of the pen just a tad to accommodate these oversize tips. Now my pen is not only a serious spike (and I love to fiddle with the bolt.. calming) but it writes beautifully (glides is a more accurate description!

Product as shown and fits in the pen, but ink dried out fast in package

I want to be clear, the seller doesn't make these and I don't blame them for the fact that they are not good. They feel rough when writing, frequently stop working, leaving numerous blank spots on the page. It almost feels like the ink is drying inside of the sealed cartridge and can't flow. All of this together makes the two (high-end and expensive) pens I use these in virtually unusable. I will not buy this brand again and caution anyone else from doing so. As for the seller, the price was less than others (but do reflect the quality of the items) and they were received quickly as described

I needed a refill for a very nice Newhall Street pen I have. They are out of business, but this refill cartridge fits perfectly. I expect many more years of use from this pen now.

Very smooth and writes perfectly. Color is great

great refills, fit perfectly and writes very nice

Top level product But don't store for a long time

Estou muito satisfeito.
