About Wing Sung
Wing Sung (永生) is a Shanghai pen maker whose predecessor was founded in the late 1940s and which was absorbed into state-owned pen factories before being re-established as Shanghai Wing Sung Co., Ltd. It was one of China's largest pen producers and is known today for very low-cost pens, several of which openly reinterpret Western designs, such as the 3008 piston demonstrator, the 601 aerometric and the 699 vacuum filler. Quality is generally regarded as high relative to the price, which ranges from a few dollars to around $40.
How to fill the Wing Sung 9181
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 Wing Sung 9181 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 9181
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.
