TWSBI: pens, ink bottles and accessories

TWSBI is a Taiwanese writing instrument brand best known for its fountain pens with integrated filling systems, characterised by modern and often transparent designs that allow the internal mechanism and ink level to remain visible.
Our catalogue features a wide selection of TWSBI fountain pens, together with inks, nibs and accessories. Among the best-known collections are ECO, Diamond 580, Diamond Mini, VAC 700R, Swipe and GO, available in numerous colours and special editions.

The History of TWSBI
TWSBI was created from the experience of Taiwan-based Ta Shin Precision, a company with a long history in manufacturing components and working with plastics and metals. After decades of manufacturing experience, the company developed its own brand dedicated to writing instruments.
The name TWSBI derives from a reinterpretation of “San Wen Tong”, an expression connected with Chinese culture and calligraphy, combined with “Bi”, a term associated with writing instruments.
From its earliest collections, TWSBI has chosen to highlight the technical side of the fountain pen, using transparent or translucent bodies and integrated filling systems that allow the internal mechanism of the pen to be seen.

TWSBI Fountain Pens
The TWSBI ECO is one of the brand's best-known fountain pens. It features an integrated piston filling system and is available in numerous colour combinations, including special editions and finishes that are regularly added to the range.
The Diamond 580 family is another cornerstone of the TWSBI collection, combining a piston filling system with a design that showcases the transparent ink reservoir and internal mechanism. The more compact Diamond Mini complements the range.
The VAC 700R uses a vacuum filling system and is designed for those looking for a fountain pen with a large ink capacity. Models such as the Swipe and GO complete the collection, interpreting the TWSBI philosophy with different filling systems and price points.
Our catalogue also includes TWSBI nibs, inks and accessories, useful for maintaining and customising your pens.
