It isn't about nibs, Montegrappa is about design. They create an accessory, not a pen. They create ridiculous ostentatious pens which I'm ridiculously enamored by. I still don't own a Montegrappa, but I'm actually planning on a ballpoint Ducale Murano to round out my pen collection. It helps that this particular model is rather tame and discreetly elegant. Which is why I''ll be getting only this model BP, and not their other, sometimes monstrous and always much more expensive, offerings.
That said, if a ballpoint Ducale Murano in the color I want shows up on MD, looking at the price on this drop, I don't know that it will be more cost-effective to buy from here than from one of European online shops with a discount code from SBRE Brown and sans VAT, since I'm outside the EU.
