About TWSBI:

With 50 years of experience in pen making, Taiwanese manufacturer TWSBI is beloved for its high quality writing tools at affordable prices. Most of their pens are made with transparent barrels, allowing you to develop your own technique and understanding of a pen's particular inkflow.  

TWSBI's name comes from the phrase "Hall of Three Cultures" or San Wen Tong in Chinese. The phrase San Wen Tong recalls the Hall of the Three Rare Treasures, created by Emperor Qianlong as a memorial to three great masterpieces of Chinese calligraphy, with the character Wen translating to "language and culture." When reversed, the initials of the phrase San Wen Tong transform into "TWS". The last letters "Bi" was added with its literal meaning of "writing instruments". The two segments come together to create TWSBI.

Their mission is to inspire and recapture the romanticism of art and literature…starting with the pen.
