Schmidt 3 Pack easyFLOW 9000 - Blue Ink

In my book Schmidt 9000 M is the best refill cartridge for Parker pens. I prefer blue ink, in a dark hue, and smooth delivery. Gel pens can deliver in the color, but not as smooth. Plus, gels are more likely to ruin a shirt when I forget to retract the point before putting the pen back in my pocket. So, oil based ballpoints only for me.I've tried several others. For comparison:* Parker Quinkflow Medium Point are simply too light in color for me.* Leuchtturm Bold Point Royal Blue are darker, but tend to have problems starting (fine once you get the ink flowing, but first stroke is often too light).* Monteverdi Blue/Black Medium is a close second to Schmidt. Very smooth, though surprisingly not quite as dark as I expected considering the Blue/Black color name. Still much darker than Parker and a little darker than Leuchtturm, though.* Schmidt 9000 Medium in Blue is the smoothest, and by far the darkest blue. It does lean a little more toward purple than the others, which suits me fine. Still blue, but a warmer shade of blue. And it delivers a good solid line from the first stroke.

These are absolutely the smoothest refill I've ever used. The color is great and looks good on paper.

These work perfectly for my pen. The ink flows nicely and they last for a long time!

I am not a fan of the Qink cartridges included with Parker pens - relatively dull and lifeless compared to gel pen inks. This Easyflow 9000 cartridge fixes all that. It leaves a nice line that pops off the page, and I have not had any real problems with smearing. it also appears to be water resistant, and is a good value compared to other options.My only issue is it doesn't play well with highlighters - even a day later trying to highlight Easyflow 9000 text with my Sharpie or BIC highlighters causes noticeable smearing / feathering (and I highlight a lot). By comparison my other go to, the Jetstream SXR-600, has no problems with highlighting. But since the SXR-600 doesn't currently come with blue ink, I am using the Easyflow for my blue pens.Overall recommended.

I dislike regular ballpoint refills. Too much friction, and the ink always seems faint to me. Gels are more my style: They glide; the ink is *dark*. But see, with a gel, you can never get those gooey effects that are possible with a ballpoint...EasyFlow 9000 is apparently some kind hybrid between ballpoint and gel (?). Anyhow you get all the gel benefits + it's a paste, so there's some goo. You can see and feel that what you're laying down on the page is *thick*. To me, they're dreamy. First time I had a 9000 in a Retro 51 Tornado, I was like BOOM. I set about systematically replacing everything in my (1) Levenger pens, (2) Retro 51 pens, (3) Karas pens.One disappointment. They will not go into a modern Sensa. Try it. There's a tiny thickness issue on the back end of the 9000 that prevents it from engaging with the Sensa guts. Really too bad, ’cuz a 9000 would have been perfect, completely in accord with the whole point of a Sensa...One final point. These things are made by Schmidt in Germany. I have to say, that is a company I trust. Their fountain pen nibs are special. Levenger FPs have ’em. I see there are many reviews that complain of 9000s skipping, leaking, etc. Not my experience. I mean, I guess they skip a teeny bit every once in a blue moon...

When I first put pen to paper with one of these cartridges I was giddy. Smooth like a gel pen but with the promise of much longer write out length. But after just one cartridge I’m not so sure. The stories about skipping are true. At times I would be writing merrily along and then suddenly I can’t get it to write. Reach over and write on another piece of paper and it’s all fine. Go back to the page where it skipped and it still won’t write. What? And now the same cartridge has transitioned from skipping to leaking. It’s not dripping like a fountain pen but there can often be blobs of ink around the end of the pen including the spring. Makes quite a mess. I’m thinking for me a fountain pen is actually less frustrating which is a bit of a disappointment. I was looking for a pen that was a little friendlier for travel.

Great refills, better than Parker brand ones and fit in same pens

I had 1 pen cartridge that worked properly out of a 3 pack. 2 of the pens carts skip so bad that I had to stop using the pen I put them in. Pretty disappointed with the overall performance. When it works it works well but it's definitely hit or miss.
