## Questions & Answers

**Q: Does the tip retract? I'm worried about putting it in my pocket.**
A: It does not retract. I've got three of these for each jacket I wear so I don't worry about forgetting to take a pencil. So far no problems with the tip...

**Q: is the body and cap a metal material**
A: No the body and eraser cap are plastic material. However the grip, the end cap, and the lead sleeve seem to be metal.

**Q: Do you need to buy a special kind of lead for it?**
A: Any 0.5mm lead will work, but the specific Kurotoga lead is softer on the outside and is purportedly more effective with the mechanism.  For very dark writing, I prefer Neox lead but it can smudge/smear a little.  My second favorite is Ain Stein lead, which almost never smudges and lasts a little longer (not quite as soft as Neox).

**Q: How durable is this? I am a graduate student in EE and math and break so many of the best mechanical pencils from staples and other office stores.**
A: I actually bought this mp to add to my mechanical pencil collection.  I now have about eight mps, all different.  Therefore, I could not provide any info regarding its durability.  I can say that this is a beautiful, finely crafted instrument.  It may be the best in terms of appearance.  I really don't think you would go wrong if you selected this one.  Best of luck!!
