I like to have my pens filled with my favourite inks, which are often pigmented/ bulletproof.
Suffice to say, these pens often dry out in most my pens. TWSBI Go, TWSBI Classic, Sheaffer Prelude evaporate quite a bit.
I know that platinums are supposedly some of the best pens in this category but they are pricey and as I favour broad nibs, their broad seems to be equal to an European medium.
And the music nib makes it too expensive for my budget.

So what are the pens that don't dry out for you?

Thanks...
