How to fill the Luoshi Labyrinth

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 Labyrinth

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.
