## 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

### ⭐⭐⭐⭐⭐ Small point, big love
*by C***Z on February 20, 2026*

Usually I hate a smaller point, not this one! Love the way this writes. Love the color. Easy to hold and writes so smooth. I have had no issues with smear or leaking, love to carry this one in my purse but really love it in my planner. Great price and will investigate refills!
