With a history of over 40 years of production, including the manufacturing of high-end pens for other brands, Ta Shin Precision has decided to sell under their own brand, TWSBI. The name TWSBI is composed of TWS and BI. 'TWS' are the reversed initials of the expression 'San Wen Tong', translated as Hall of Three Cultures, and 'BI' literally means writing instrument.
