Extra
A model in Omas's fountain pen lineup. Specs below reflect the typical configuration across Omas's core range.
This sits at the upper end of the hobby — a pen most people buy after they already know their nib and grip preferences, often as a long-term or milestone piece rather than a daily-carry first pen.

About Omas
OMAS (Officina Meccanica Armando Simoni) was founded in Bologna in 1925 by Armando Simoni and became one of Italy's most collected pen makers, known for celluloid bodies, faceted designs and models such as the Paragon, Ogiva and the twelve-sided 360. After ownership passed through LVMH, Hengdeli and O-Luxe, the company was liquidated in January 2016 and the brand was revived in 2023, with production returning to Bologna using original tooling and remaining celluloid stock. Pens are piston-filled with 18k gold nibs and sit in the luxury price tier.
How to fill the Omas Extra
Unscrew the piston knob at the back of the pen, submerge the nib fully in a bottle of ink, and slowly turn the knob counter-clockwise then clockwise to draw ink in. Piston fillers hold significantly more ink than a standard cartridge — often enough for several weeks of regular writing — at the cost of being limited to bottled ink only.
Choosing a nib size
Nib size determines line width, not writing pressure — fountain pens are meant to glide, never press. Extra-fine (EF) suits small, dense handwriting and thin paper; fine (F) is the most broadly recommended default; medium (M) shows more ink character and shading; broad (B) and stub grinds favor bold, expressive strokes and calligraphy-adjacent writing. The Extra's gold nib will also flex slightly with pressure, giving line variation that a steel nib of the same size won't produce.
Keeping it clean
Because Omas Extra holds a larger ink reserve, a full flush every 4–6 weeks (or whenever you switch colors) keeps the feed running cleanly. Inktend's cleaning reminder is tuned to a 21-day baseline and adjusts naturally to how often you actually refill.
Pairing inks with the Extra
High-capacity fillers like this one are the natural home for sheening and shading inks; you'll actually see the color develop across a full page instead of running out mid-paragraph.
