Modula Flame 6 - Santini Italia Fountain pens and nibs Made in Italy

At the heart of Modula is its defining innovation: a fully interchangeable nib 
system. With a simple unscrewing motion, you can swap between two 
distinct nib sizes—a larger No. 8 nib or a more compact No. 6 nib.
This modularity allows you to tailor the pen to your mood, task, or personal 
style without compromise.
Each nib is crafted in-house from 14kt gold, offered in a range of sizes to suit 
every writing preference.

You can also order an extra nib number 6 or 8 in different sizes.
