Collection: TWISBI

TWSBI is a Taiwanese fountain pen brand established in 2009 by Ta Shin Precision, a company with over 50 years of experience in precision manufacturing for global brands. After decades of producing components for other companies, they launched their own brand to create high-quality writing instruments under their own name.

The brand name “TWSBI” comes from the Chinese phrase “San Wen Tong” (Hall of Three Cultures), with “Bi” meaning “writing instrument,” reflecting the company’s dedication to writing, culture, and craftsmanship.

TWSBI is best known for its affordable piston-fill and vacuum-fill fountain pens, often featuring transparent “demonstrator” designs that allow users to see the ink inside. Popular models like the Eco, Diamond 580, and Vac700R have made the brand a favorite among both beginners and pen enthusiasts.

The company is widely appreciated for offering high-performance fountain pens at excellent value, combining precision engineering, user-serviceable designs, and a strong focus on writing experience.
