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

Perfect ink. Does not skip. Much cheaper than other brands, though their quality is much better. These refills fit my Rotring 600 ballpoint/gel pen perfectly, so I believe they are compatible with whatever pen uses a standard G2. I mainly use these refills in my Rotring 600 but I leave a bunch of these refills everywhere to use as a quick pen; they’re very versatile - so small and easy to keep everywhere and anywhere. I have one or two in my purse, car, pocket, etc. at all times. Only issue - if you have large hands like my husband, it’s difficult to use them as is (not inside a pen); but I don’t have that problem. Beautiful blue ink; fully saturated and dark black ink. The quality is better than any other ink I’ve purchased. Drawing; writing; this ink makes me want to use paper instead of my iPad.

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.

Overall I am pleased. I have a favorite pen for work and have used ballpoint refills for years. Recently we approved the use of gel pens (because our office supplier cannot get ballpoint pens right now lol) so I ordered these straight away. They arrived with 3 of the refills having lost the protective cap and had leaked slightly. I used one of those first and they write smooth and have not leaked any further. The ball leaves a smooth skip free line, and the gel ink is just a joy to write with (terminus me of a smooth fountain pen). These fit my brass pen perfectly and I have not had any other issues. I do worry about the other 2 leakers drying out before I can use them, but we shall see.

Worked great.

I just got these refills, 10 refills for a price that is less than half of what a regular Parker refill would be; now I just need to use them to see how long they last and how well my pen will write with them. My test run is that I have over two hundred letters and postcards to write before November 3rd!!

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

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

Amazing price and fast delivery

Very smooth and writes perfectly. Color is great

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

They do the job and they don't leak, which was a problem in tactical pens that don't write much.

Estou muito satisfeito.

the one i received leaks a lot! ruined my scrub suit! i complained and amazon accepted the return
