TWSBI Pipe Pen Filler For Refilling Converters and TWSBI Fountain Pens

A 4-inch stainless steel snorkel that extends the reach of a fountain pen or converter into deep, narrow, or nearly empty ink bottles. Attaches directly to compatible pen barrels and converters; the pen's own piston or the converter's mechanism does the drawing. Why it's special: Reaches the bottom of tall, narrow, or low-fill bottles where the pen body won't fit — including sample vials Acts as a direct extension of the pen: the grip section comes off and the pipe threads on in its place Stainless steel throughout, no plastic in the ink path Fits the TWSBI Diamond 580 line, Mini, Classic, and Precision, plus most standard international converters and TWSBI's own Spring-Loaded and Piston converters used in the SWIPE Ships with protective end caps to discard before first use Specs: Material: Stainless steel Length: 4 in (10 cm) Compatible with: TWSBI Diamond 580 / 580AL / 580ALR / Mini, Classic, Precision; most standard international converters; TWSBI Spring-Loaded and Piston converters
