About Asvine
Asvine is a Chinese pen brand based in Guangdong that began selling under its own name around 2020, having previously produced pens for other labels; it is closely connected to the makers behind Hongdian. It is known for offering filling systems normally found on far more expensive pens, notably the P-series piston fillers (P20, P30, P36, P50) and the V-series vacuum fillers (V126, V200). Bodies are usually acrylic, often demonstrators, and most models accept standard JoWo or Bock #6 nibs, with prices generally between $20 and $45.
How to fill the Asvine J16
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.
Keeping it clean
Because Asvine J16 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 J16
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.
