JETSTREAM PRIME Twist Mechanism Accessory Pack 0.5mm

My job requires me to often fill out forms or write things down. Over time, I have become particular about pens as I have to use one extensively. I prefer a fine-tip pen, 0.5 mm being ideal for my purposes. The Jetstream Prime Twist refill does come in medium and larger tips as well. This is a Parker style refill so it could be used in any pen that takes a Parker refill. This Jetstream refill made by Uni-Ball(Uni?) a brand manufactured by the Mitsubishi Pencil Co. Apparently, the MPC is not affiliated in any with the Mitsubishi automotive and heavy industries conglomerate we are all familiar with despite having the same logo. The Uni brand has a good reputation for quality writing instruments. This Jetstream ink is a low viscosity oil-based ink designed to compete with gel-based inks. It claims the crisp sharpness and fast drying of a gel ink but with the smoothness, waterproofness and longevity of an oil based ink. Jetstream ink is held in high regard by Jet Pens....and they'd know. Prior to this, my absolute favorite fine-tip Parker refill has been the Ohto Flash-Dry Gel 0.5mm. It's a pleasure to write with. The best. But.....they are hard to come by and expensive to boot at $5 per refill cartridge. So...I needed a more economic alternative. How did the Jetstream Prime Twist refill stack up? I am pleased to report, it's as good or better than my beloved Ohto Flash-Dry ink. No smudges, smooth, crisp lines. It's really quite good. I was very surprised that an oil-based ink could write as nice as this. I will definitely be buying this one in the future. You won't be disappointed if you give this one a try. Five stars Uni-Ball!

It sounds silly to review a pen. But all pens are not created the same. This is a Japanese brand known for developing what many feel is the smoothest and best ink pen. This version particularly is felt to be the GOAT of pens. Highly reccomend. Writes smoothly and consistently. Doesn't smear. The fine point is in my opinion almost too fine. It's like writing with a needle dipped in ink.

This refill fits all Parker Style G2 sizes. This is my FAVORITE fine-tip ink. Writes beautifully, and makes extremely even and thin lines. Great for fine details and even cross hatching. Good dark color. See attached photo. This refill made the thinner black lines (the blue lines is a different brand if y'all interested). The top thick lines with bleed off is a totally different pen refill, so don't worry. I love thin extra fine lines, especially because I like to sketch alot. So far, I have not seen a SINGLE example of bleed off or pooling of ink from this. After doing research, nearly everyone suggests this pen refill for Parker style G2. I would HIGHLY recommend this for people who either like thin lines while writing, or doing little pen sketches in a notebook. Great pen refill and in my opinion well worth the price. Will buy this whenever my ink runs out.

These cartridges are TOTALLY awesome! Most pen cartridges require you to draw a few lines to get the ink flowing, or have the ink flowing so freely that the letters are splotchy and not crisp. I searched and searched and finally found these - my search is now over! These let the ink flow from the first instant and never get too much ink on the page. Be sire to get the ones made in Japan! My theory is that people writing in Japanese characters need to make very clear lines, so they developed these pens. Whatever the reason, these just WORK! Every time, all the time.

This parker-style refill is really different than others. It's got a super fine ball point tip that is a little bit like writing with a pin. I'd describe it as a little bit scratchy. Yet, it has a lot of flow and very saturated black ink. That combination of smooth and scratchy is unlike any other pen I've written with. I like fine point pens as they clarify my writing. This also has ink which they say is a hybrid of gel and normal ball point which is exactly how it feels. I'm not a big fan of gel pens as they're too slippery for me -- they don't have a feeling of contact with the paper that I like. This is slightly like that but not so much that it annoys me. Very reliable -- does not skip.

I keep extra on hand as I would be super sad if these went obsolete. Consistent, great quality.

So smooth and isnt spotty even from just started using. The lines are thin with the smoothness of a rollerball pen

I was looking for a good refill for my Parker-style pens, as the generic ink included with some was prone to smearing. One refill I tried was the Uniball Jetstream, in both Fine Point (0.5mm) and Medium Point (0.7mm). Ultimately I decided the Fine 0.5mm is great, but a bit thinner than I prefer and a tiny bit scratchy on some paper. The Medium 0.7mm is perfect for me - surprisingly smooth. Both have no issues with smearing or skips. I would recommend either one to anyone needing a Parker hybrid ballpoint refill - 0.5mm for a finer line with some feedback, 0.7mm refill for smoother writing.

This is an excellent alternative to the standard Parker refills. The ink flows very smoothly with minimal pressure needed, and the nib lays down a consistent line. I have found Parker refills lay down an inconsistent line, and the standard 1.0mm nib on those feels very "mushy". These Jetstream refills give great control and the 0.7mm nib gives you better performance and "wetness"/consistency. Highly recommend!

Very smooth writer, nice and sharp line. Haven’t had any hard starts or smearing issues at all.

As promised new unused uni sxr-600-07. The best refill/pen Ive ever used.

Incredible writing experience. Probably the best when it comes to ballpoints. Only downfall is the price.

Best G2 style refill ever. Hands down. Ink flows dark and smooth without the normal skip you get with other ballpoint refills. Went to replace my Parker Jotter and rOtring 600, and it was the best thing I did. Now they both write perfectly all cause of this beauty.
