About Faber-Castell
Founded near Nuremberg in 1761, Faber-Castell is one of the oldest manufacturers of writing instruments in the world, still run by the same family after eight generations.
How to fill the Faber-Castell Essentio
Fill it two ways: snap in a pre-filled international cartridge for convenience, or use a converter — a small plunger or twist mechanism that installs the same way a cartridge does — to draw ink from any bottle. The converter route opens up the entire world of bottled ink, which is where most of the hobby's color variety lives.
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.
Keeping it clean
A quick flush with cool water every time you switch ink colors — and a full clean every 4–6 weeks of regular use — is enough to keep the nib and feed performing well. Inktend's cleaning reminder is tuned to a 21-day baseline and adjusts naturally to how often you actually refill.
Pairing inks with the Essentio
Because refills are quick with a cartridge or converter, this is a good pen for rotating through several colors rather than committing to one — sample vials work especially well here. Browse the ink library to find a first bottle.
