## Questions & Answers

**Q: Will Pilot Frixion .5mm refills fit in this pen? ( If so, could fix the ink quality problem one reviewer mentioned.)**
A: You need to get the .5mm refills that are designed for the multi pen. Unfortunately they are VERY different and have a lot less ink in them then the standard refills.

**Q: Are these erasable pens (with an eraser at the tip of the pen)?**
A: Yes, and they work great!  The "frixion" name refers to the fact that these pens are erasable by applying friction to them with a silicone eraser.

**Q: Can I use a 0.7mm refill to replace it?**
A: probably, I would only try one pen at a time to see if it fits.

**Q: How do you change the ink refill on this pen?**
A: unscrew the pen and slide down the lever of whichever color you are changing. Pull on the ink cartridge until it pops out then just put the new cartridge into the hole you pulled the other out of and push it in. Screw pen back together
