## Questions & Answers

**Q: The picture shows 2 pens, yet the description "in the box" says 3 pens. Which is correct?**
A: 2

**Q: Can you buy refills for these, and if so where?**
A: I do declare that you can buy them. I have seen them on Amazon (albeit a while back) but in my opinion you are better off buying another pen. The refills aew probably as expensive as the pens!

**Q: 0.4 mm or 1mm as it says both in the write up  ?**
A: I've bought these (in blue) on more than one occasion and have never noticed that! My ones have 1.0 stamped on them which I take to mean 1mm. When I write with them it doesn't look particularly 'skinny' so my guess would be that it is actually 1mm and not 0.4mm. Sorry I can't be any more help.
