## Questions & Answers

**Q: Does it fit Swarovski Stardust pens?**
A: I don't know about the Stardust pens but I know it fits the Swarovski Lady Crystalline pens.

**Q: If you have tried this refill with a livescribe pen, does it fit/mod? (livescribe refills are about 2.25 inches long x ~2.5mm wide)**
A: Tested: fits nicely and the Livescribe 3 pen also recognizes the ink when writing.

**Q: Is there a fine point version?**
A: The refills I received, both blue and black, were medium point.

**Q: Is this refill as pictured with just the silver tip only or is the product received the silver and black tip refill?**
A: Normally the tip color will correspond to the ink color.  In this case the tips should be black.  Jim
