@freemo Neat! I've never written with a fountain pen. What exactly is a 'Flex Pen'?
@Surasanji A flex nib is a nib that easilt bends under pressure. When it does the tines spread out and the line width drastically increases. This lets you control line width as you write to create fancy looking letters. Its a form of cursive italic that takes a lot of practice, the other easier form just uses a fixed wide nib and you vary line width by angle.
A flex nib, if its a good at flex, feels more like a paint brush.
@Surasanji Well clearly, no one in their right mind would expect me to sign something if I dont have a cape with me!
They actually have a type of fude pen that has a literal paint brush for a tip. It is filled with fountain pen ink. They cost like $6 and i ordered one of them too.
