Nibs guide

The heart of every SCRIBO fountain pen is the nib and we do it in gold; every nib is assembled together with ebonite feeders only, to get the best available handwriting performance; our nibs, in either the classic 18-carat alloy or the special Extra-Flexible 14-carat alloy, grant elasticity, mechanical memory and softness that highlights every fountain pen writing quality.

In particular, SCRIBO Extra-Flexible nib, a real jewel for handwriting, reached the highest hand-writing performance thanks to the continuous technical improvements that have been made during our previous experience.
