Does this fit a standard #6 nib?

no the nib creaper uses a #2 the Ahab and Konrad are #6 nibs

Can I put white ink in this pen? If so what kind is best?

Have you tried D'Artrementis white ink? It is made for fountain pens.

Can we see a writing sample?

Better check youtube. Personally I was hoping for little more flex.

I'm a bit confused. Is this listing for a clear demo pen or a blue lapis pen? The title and the description don't match.

It's the clear demonstrator of title and photo.Description is probably just copy-pasted from a similar listing. I don't think I even read it before ordering - Amazon have been successfully deemphasizing it (at least on mobile).
