TWSBI Fountain Pens

TWSBI logo

Fountain pens are what TWSBI are best known for. Unlike most new pen makers, when TWSBI started manufacturing their own range of pens (after years of making pens on behalf of other luxury brands) they went firmly after the enthusiast market. Rather than making simple cartridge-filled pens, they made the sort of quality piston-filler and vacuum-filler pens fountain pen enthusiasts had been missing for many years.
