Compatible PARKER G2 Type GEL Ink Refills Pelican Fibercastle Visconti Monte Grappa Monte Delta Fischer KAWECO Marlen Omas Smith & Wesson Schaeffer Porsche (Metal - BlueBlack, 0.5mm)

I am so impressed with this ink. The reviews were mixed, but I couldn’t pass up on the hope and value of these refills. The quality of this ink is excellent! I actually first discovered this ink brand when I picked up a friends Parker Jotter to write in a birthday card. I was so impressed with how smoothly it was writing, that I opened it up like a nerd to see what kind of ink was in there. It was this! I immediately found it on Amazon and placed an order. When the ink arrived I excitedly swapped my Kaweco ink in my Kaweco Sport Ballpoint pen, and it does not disappoint! First, it fits perfectly, it does not hard start or skip, it flows smoothly, and I will absolutely be going with this ink whenever and wherever possible. Wonderful value for the money. It just goes to show that more expensive does not always mean better!

Perfect fit for my rOtring 600 pen. I was also able to fit these into my O-light pen. I had to cut it down to size with scissors which was easy and mess free. Just cut the plastic end as close as possible without cutting into the ink section. Tip: keep the original "metal" ink cartridge for Olight pen. You need it to charge the battery. This ink runs smooth and I highly recommend for these pens. The picture shows how they fit.

Nice option for a gel refill in this format. I don't think it's quite as good as a factory G2, but good substitute if you need this type of cartridge.

The ink is a brighter blue color and it flows really good at this point. If they continue to flow well, I might prefer these over my space pen refills. One thing I like is that the refill is clear plastic so it's easy to quickly check the ink level. As we know, Gel ink refills tend to deplete quicker. At about $1 per refill, I think these offer a great value. Tested these with F-701 pens and they are operating good. Trimmed the plug back to just a small amount above the refill to give the mechanism a flat surface to operate against, used the original 701 spring and didn't trim the plastic insert in the writing tip...good result.

Worst part of "Last a long time, never need repair" is I wore a few out, but I don't remember where I put the rest of them when I'm finally gettin' my Round Twoit.

Acts like they are dried up

There is enough variation in the diameters of the refills' tips that half of them will not fit through the tips of certain of my pens, while the other half will. They also have a tendency to ghost or simply stop writing with plenty of ink remaining. When they fit and work, they do so quite well, and this "Blueblack" ink color is excellent.

I bought this product to get a fine point gel refill that is compatible with Parker style pens. So far, I have been very pleased. The blue black color is dark with just a hint of blue. It is well saturated. It writes smoothly with little effort or pressure. It is a true fine point (0.5). I plan on buying at least one more set of refills in either blue or black for variety. The price is great at just $1 per refill (actual Parker refills are often $7-8 each).

In my experience the quantity of ink is less as compared to regular brands. As a redult refill wont last long.

Fantastic refill. I love dark blue ink, but Parker-style refills tend to be too thick. At 0.5 MM, it's nice and fine, but also smooth and dark. However, either depth of the cutouts near the base or the taper of the ink chamber doesn't quite work in a Parker Jotter, so it won't always pop back into the barrel. Needs a little push. It seems to compress the spring in a strange way to prevent it from popping it back in. Other than that, this is a good quality refill if you like that Zebra Sarasa feel but have Parker-style pens.
