World Tree - Ebony
A model in Wancher's fountain pen lineup. Specs below reflect the typical configuration across Wancher'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 Wancher
Wancher is a Japanese pen brand established in 2011 in Bungotakada, Oita, by Okagaki Taizo. It is best known for the Dream Pen line in Japanese ebonite, urushi lacquer and maki-e, alongside cheaper resin models such as the Kaleido. Pens use standard international cartridges or converters and are sold with JoWo #6 steel nibs or Wancher's own 18K gold nibs; prices run from about $100 to well over $1,000 for hand-decorated pieces.
How to fill the Wancher World Tree - Ebony
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. The World Tree - Ebony'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
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 World Tree - Ebony
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.
