For the full story behind the brand, see our TWSBI Brand Guide. Here is a guide to the current TWSBI fountain pen range.
Entry Level
The Go and Swipe are TWSBI's most accessible models, ideal for beginners or younger writers. The Go uses a spring-loaded filling mechanism, while the Swipe is the only TWSBI that accepts standard international cartridges as well as a converter -- making it the most flexible option for those who want the choice.
The Eco Range
The Eco and Eco-T are TWSBI's best-selling models and among the most popular fountain pens in the world at their price point. Piston-fill, transparent, and available in a wide range of colours and limited editions, the Eco offers exceptional value. The Eco-T features a triangular grip section for added comfort.
Diamond 580
The Diamond 580 is slightly larger than the Eco, with a faceted barrel and the same reliable piston-fill mechanism. A step up in presence and refinement without a dramatic increase in price.
Vac 700R
The Vac 700R is TWSBI's larger vacuum-fill pen, offering an impressive ink capacity and a satisfying filling ritual. Well suited to writers who go through a lot of ink.
Mini Models
The Diamond Mini and Vac Mini are compact versions of their full-sized counterparts -- ideal for those who prefer a smaller pen or want a portable option for travel.
Nibs, Inks, and Accessories
All TWSBI fountain pens are available with a choice of nib widths from extra fine to 1.1mm stub. Presentation boxes from the Eco upwards include a small spanner and silicone grease for optional maintenance. TWSBI also produce their own fountain pen inks, ink bottles, mechanical pencils, converters, and spare nibs.
