About Skogsy Pens
Skogsy Pens is an American husband-and-wife pen making operation started by Zach Skogsberg, who turned his first pens in spring 2021 after buying a wood lathe. The brand is known for compact handmade fountain pens with wide grip sections, unusual materials such as micarta, and models like the Cholla and the Low Volume Eyedropper. Skogsy sells through its website and has become a regular presence at US pen shows.
How to fill the Skogsy Pens Cholla 16MM
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 Cholla 16MM
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.
