uniball Jetstream Extra Fine Point Roller Ball Pens Refills for Multi Pen Type-0.5mm-black Ink-value Set of 5

There's a special pen called the uni-ball Jetstream Multi Pen Type that some people use a lot. To make sure the pen keeps working well, you need to change the ink inside it sometimes. Luckily, there are special ink refills you can buy that work really well with this pen. These refills make writing with the pen super smooth and easy, and the ink dries quickly so it doesn't smudge. You can buy a set of five refills at once, which is a good deal if you use the pen a lot. Just remember, these refills only work with the Jetstream Multi Pen Type, not regular Jet Stream pens.

Exactly what I needed.

Finding the right ones was a bit of a nightmare. Lots of listings, lots of reviews talking about off-brand advertised with UNI packaging, sandwich bags, wrong physical sizes everywhere. Based on a few solid reviews, I ordered this (5) black refill set. This was it! Exact OEM MATCH, individually packed in OEM wrappers, set of 5 in professional packaging. It writes like the old one did, I believe it's the real deal. When I need color replacements, I'll look for the same seller and packaging.

I think the problem with all the negative reviews is that they bought the wrong product. This is designed specifically for the Uni-ball Jetstream EXtra Fine Point Roller Ball Pens 0.5 mm. That's why it's short, that's why it's very fine and precise. And that's why I am buying it over and over even though it's pricy. So dear other customers, please buy the right things for your pen and dont make good products go down with negative feedback just because of your obliviousness. ( I am a UC Berkeley student not a seller btw, I am just annoyed with so many mistakes of all kinds that people make these days that result at the lost of so many innocent things such as the euthanizing of those grizzly bears in YellowStones National Park and so on)Ps: The picture is the pen that these refills are for

Very smooth writing on journal pages. No smearing. I'm left handed, so I value pen refills that are quick to dry and don't smear as my hand rubs over the writing.

Someone actually mentioned that this refill will work with my uni alpha gel multipen, and it does! So happy to find a finer pen tip than the usual 0.7 for my alpha gel. Writes smoothly and the pigmentation is actually darker than the original refills. I've only opened one for use so not sure if the other refills are good or not, but definitely happy to find this fits my alpha gel multipen and will be ordering again for other color refills.

DO NOT BUY THIS for your single use Pen.It's meant to go with the other colors (red & Blue) in a MULTI-USE-Pen.It is NOT a Uni 0.5 mm Refill. Now I'm stuck with 5 refills for a pen I do not have.Wasted MONEY!

I absolutely adore my Uni-ball jetstream Extra Fine Point Roller Ball Pen in 0.5mm. When I ran out of the black ink, I placed this order as a replacement. Works exactly as advertised - just unscrew the pen tip, pull out the empty cartridge, and stick in the new one. Most importantly, I was happy to see that this replacement glides just as smoothly as the original.
