Uni-ball Jetstream Fine Point Roller Ball Pens Refills for Standard Pen Type -0.7mm-blue Ink-value Set of 5

Had a difficult time finding 0.07 refills for my favorite Jetstream pens. This is exactly the right fit and I tested all the refill cartridges. All write smoothly, no blobbing, and I'm so glad to have found these on Amazon. My local stationery store didn't have them on their shelf, and they were much costlier to order there.

I’m picky about my ink, and these Uni-ball Jetstream 0.7mm refills hit the sweet spot—smooth writing, no smudging, no skipping. They make even quick notes feel effortless. I’ve tried a lot of pens, but I always come back to these. The ink dries fast enough that I don’t end up with smudges (even when I’m scribbling something down in a hurry). Plus, they last a good while, so I’m not constantly swapping them out. If you already use Jetstream pens, these are a no-brainer. If you don’t—maybe it’s time to start. I don’t see myself switching anytime soon.

Could not find refills anywhere else! Drives me crazy that Walmart & Target sell refillable pens and pencils but never have the refills. Perfect refill for my Uni-ball Jetstream Fine Point Roller Ball Pen. Ink is smooth, refill is easy to put in the pen (unscrew pen, being careful not to drop spring, take out old ink thing and toss, put in the refill, pull the little plastic bit off the tip, put the spring back on, rescrew pen together). This is my favorite pen in both 1.0 and .07 --I don't use any other. I have them stashed all over the house where I need them, labeled for that location so I don't misplace them and my kids can't mistake them for their own! So happy to find this pack of 5 refills on Amazon.com!!!

Some Jetstreams last to the last drop, others die halfway through. I've found a way to fix that failure, but I've not tried it with Jetstream yet. Get a hypodermic needle, the smaller size. Dull the needle a little bit with a file or sharpening stone (you may find the 5 pack in Amazon), so you dont stick yourself. Fill the cavity with air and push the needle into the end of the cartridge, holding over a piece of scratch paper in case ink runs out, like it will with a rollerball. Push down on the plunger with your thumb to build up some pressure in the cartridge, and rub the tip over some cloth or paper to try to clear the ball point of any dried ink, paper pulp or debris that may have clogged the tip. Alcohol soaks wont do it. You'd be surprised how an old cartridge might be brought back, but not always. You can use bigger needles or take off the needle for rollerballs sometimes. Now they have these new rubber grip pens I'm going to enjoy UniBall again. Just for kicks, you can put a Signo's silver tip on some of these ballpoints. Do try to keep all springs for later use, if you like to switch cartridges around in different pens. You can twist out a big paper clip to save springs on, and bend the tips of the clip together to keep the springs on it.

These refills work like the originals. I kept three empty pens, and now I do not have to buy, store, and throw away a whole pen each time. Refilling my pens, I save money, space, and waste.

I rely on the Uniball jet stream fine point blue pens for my daily journal writing. I bought these refills, hoping to save the plastic involved in new pens. However, I’ve already tried two of the three refills and they skip letters and sometimes whole words. Unfortunately, I will have to start buying new pens again. Very disappointed in the quality of this product. However, I waited too long after purchasing them to try them, so I can’t return them.

This is the smoothest ink on he market. You won't find a better pen refil than these. They write better than anything else I've tried. I usually put these inside a Sarasa Grand pen to make the perfect pen. I am able to write on thick porous paper and also very thin bible paper with these without any skipping l and the ink dries super fast. No smearing even with highlighters.

It's such a waste when your favorite pens have empty cartridges and it is impossible to find the right replacements. These replacements were made for the pens I love and less money than others out there on the market AND they work great!
