Loom
A minimalist hexagonal-barrel pen with a distinctive slide-open cap mechanism instead of a screw or snap cap.
A solid mid-range option once someone has decided fountain pens are a habit worth investing a bit more into.

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. This model, Loom, dates to 2016.
How to fill the Faber-Castell Loom
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, plus a full clean every 4 to 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 Loom
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.
