I'm an avid Montblanc Fountain Pen lover. So my loyalty does unfortunately lie with Montblanc. The Graaf vonFaber-Castell fountain pens have rather firm nibs compared to Montblanc's soft nibs.
I am a big fan of Graaf vonFaber-Castell pencils, I would love to own a 0.5mm mechanical pencil or a 0.5mm mechanical pencil from Caran d'Ache. I truly don't like using my 0.9mm Montblanc pencils (which are never used).
