Automatic Lead Rotation Roulette Model

Q: is the body and cap a metal material

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?

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.

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!!
