Review: A decent writing pen. - I wanted a more unique and higher end pen. This one very much piqued my interest. Design and color wise. So far, it writes very well. With my style of writing a finer tip helps me keep more legible. It is possible they have fixed past issues. Mine writes smoothly and consistently. The body is mostly plastic with a metal grip and clip. I find it comfortable and fashionable. The grip focuses the weight of the pen towards the tip. Unfortunately, mine fell out of my pocket and hit the blacktop. It survived well and has unnoticeable scars. I was not using the clip at the time. Just in my front pocket and snagged by my keys. It's a tad longer than other pens I own. The only negative I could have is with switching out the ink cartridge. It's held in there rather firmly.
Review: Best find point pen! - Love this pen. The only one I like to write with very fine point that does not run like gel it lets it be very controlled the only pin I can write with good penmanship. Very smooth and easily grilled. Comfortable.

## Questions & Answers

**Q: What refill can I use?**
A: You can use Jetstream Edge refills or Jetstream Multi refills. I don’t buy them on Amazon. Not sure if I can say this but I buy them from Tokyo Pen Shop online

**Q: How do I replace the ink pens**
A: Pull from the grip down, without twisting to expose the cartridges, then pull the cartridge you want to replace out.

**Q: How can I get the .38mm refills for this and will they fit in this pen?**
A: Uni SXR-80-38 fits this pen and is in the 0.38mm size (hence the “38” at the end).

**Q: Is there a way to tell which tip you are selecting?**
A: only if the refill is the .28 - the .38 & .5 refills look alike but write differently

### ⭐⭐⭐⭐⭐ One of the best pens ever made
*by R***N on February 18, 2026*

I love this line of pens from Uni - this pen has the lowest friction coefficient of any other pen which is perfect for long writing and fast writing. Refills are also easy to find. Good quality as well as this is full metal I believe
