Uni Jet Stream Prime High Grade multi ballpoint pen - Refill - 0.5mm - Black - SXR-200-05

Best ink refill i have usedSmooth, lasts a very long time and is economical. I love how it reacts on good paper and doesnt smear!

Bought this to use in my EDC pen, a Makerset Field Pen. Fits the pen perfectly, smooth writing, and a nice crisp thin line. Like most D1 type ink cartridges, it's not really designed for writing long letters or books as there's really not a lot of ink in it; really just for taking notes each day in your Moleskin or Field Notes books. It works well on the different paper types I tested it on. I've used other larger Uni pens and refills in the past, and this one works just like the big boys so far.As noted by another reviewer, this item shipped direct from Japan via sailboat or homing albatross, taking over a month to arrive. But arrive it did, and I wasn't in a hurry for it, so no star downgrade due to that. Just be aware.

It stopped writing properly after 2nd day of use. Ink comes out for a bit, then stops for a bit, then comes out for a bit, and so on. Words written aren’t legible on various papers.

Im more used to 5, so I’m very happy that I could swap my 7mm to a 5mm. A good refill really does make a world of difference. It’s incredibly smooth, especially compared to regular refills.

The only complaint I have is that I write at a certain angle and that causes my pen not to write as smoothly

Purchased this refill for my Uni-Jet Stream pen. Although, have not had to use it just yet it arrived it perfect condition and glad I have a replacement. Great value

Uni Jet Stream Prime high grade is the best pen I have. The replacement works great.

Gotten three of these and the first two ran dry within half a page. Maybe the third will be better but I doubt it.
