I bought a M800 2 weeks ago. it was a F nib and I really thought I wanted a F nib. But after writing with it I want a M nib now.

Will Chartpak exchange the nib for free?

If not do you know where I can get an M nib without paying a large sum?

Yes, they will.

You could also trade with someone here. There might be someone looking for an F nib.

Great, I guess I should call Chartpak Monday and see what the procedure is, thanks

They will almost certainly be able to help, but if not contact me.

Wow, They gave me an address to send it to for a free nib exchange. This was a welcome change from the Montblanc service center, where everything costs as much as a new pen.

i think you should choose B nib.

You're going to find that Chartpak is a wonderful company to deal with.

I second the recommendation on the B nib. You can always have it doctored up, plus they have a very nice line variation. All 800 M nibs I've tried are junk (compared to F's and B's from the same pens, that's M8XX)
