Jetstream Roller Ball Stick Pen, Bold Point, 1.0mm, Assorted Ink Colors, 3 Pack

Best pen refill ever! EVER!I have been using pens for over half a century and nothing has ever compared to this!I am a writer, and I do book signings, and write with a pen all day elsewhere too.I found many pens this refill fits, so I get the best of both worlds.I can use it in almost any pen made by the same company.I have introduced a lot of people to this pen and refill, and they thanked me.Put this in my favorite, most comfortable pen to use and I am in writing heaven!NO FATUGUE, effortless writing. This will spoil you into never using anything else! (Other refills seem like a drag and even a scratch by comparison)So, I get lots of them and use them up!

Every so often, Uni-ball changes the numbers on their refill packaging. If you buy refills that have a little black cap on the end, used for the non-retractable pens, you can remove the caps to use them for the retractable ones. And vice versa; save the black caps if you buy that kind, so you can use the refills for both kinds. I use both regular and retractable Jetstreams depending on where I'm using them. They're both equally great.It is very important to buy the brand-name refills from a reliable source. I once found a great bargain in different packaging, and the refills only worked halfway or not at all. The genuine refills will write until there is not one drop of ink left!

I am used to writing everything on a computer. But once in awhile I do have to write with a pen, and when I do I get cramps so fast. From the other reviews, I decided to go with Jetstream uni-ball pens for the smoothness and because I wanted a pen that is water proof for writing checks. I would say the differences between Jetstream and other ball pens aren't significantly different, but I do notice that I don't have to press down hard at all with the Jetstreams to get the ink flowing solidly. In fact, I don't notice any difference in the ink output whether I press softly or hard on the pen versus other ball pens that I own. Therefore, these Jetstreams are a lot easier on my hands. Lastly, as an added bonus, you can tell from the outside of the pen when the ink will run out without you having to unscrew the pen apart to check. I'm glad I got them and I will gladly buy them again.

This is my first experience with Jetstream ink and it is excellent. Very smooth, rarely skips (certain paper cause any pen to skip) and not much blobbing. A really great writing experience. The nice thing is how long the refills are, making it possible to remove the end plastic piece, trim to size and replace. If done carefully it can fit in pens that take Parker refills. I also found that no modification was required to fit this refill in the Pentel Tradio body, which normally takes Energel (another hybrid ink). In comparison to Energel, Jetstream is more 'oily' feeling (the smoothest ballpoint pen I've tried), while the Energel feels more 'wet' requiring even less pressure. I'm switching to Jetstream more often because it's more permanent / waterproof than Energel.

Uni-ball jetstream stick roller ball pen is the best pen I have used in my life and I am actually picky when it comes to pens and pencils. And when I found out that I could actually find the refills I was very happy. Using refills is good for the nature and good for your pocket. These work with any of the jetstream stick roller ball pens. I had the bold point and the fine point versions both of the pens and the refills and I got to experience with all the combinations over the time. I know they all work with each other and I sometimes switch just for fun. To my purposes it doesn't really matter if its bold or fine.

Have loved my Jetstream pen over the last year so I purchased a 2-pack black refill and they work perfectly --- just like the originals. Will happily use my Jetstream throughout 2021. Cheers!

I love my uni-ball Jetstream Ballpoint Pen and was able to find refills here. Writing with this ballpoint pen is a unique experience. The grip is perfect and the ink slides on the paper effortlessly.

Love this brand. Never leaks and writes so professionally.

These pens write so incredibly well - no ink blobs, very smooth, clean lines...what's not to like?

I use these refills on the pen of the same name and wouldn't use anything else. They allow for smooth and reliable writing and have the bonus of being ecological. No more disposable pens for me.

Love that you can buy the refill inserts. Great pen that glides easily and is very comfortable to hold. Highly recommended!

Smooth perfect ink flow, didn't skip. Very nice to write with

Perfect
