About Narwhal
Narwhal is the original name of the pen brand launched in 2019 and renamed Nahvalur in August 2022, the new spelling being the Icelandic word for the animal. The brand built its reputation on affordable acrylic pens that fill from a bottle rather than a cartridge, starting with the piston-filled Original and later the vacuum-filled Original Plus and the oversized ebonite Nautilus. Pens use in-house #6 stainless steel nibs, with 14K gold options on some models, and generally sell for about $50–200.
How to fill the Narwhal Horizon
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 Horizon'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 Narwhal Horizon 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 Horizon
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.
