## 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

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
