TWSBI is a Taiwanese fountain pen brand featuring affordable demonstrators with pistons. TWSBI's name stands for the phrase 三文堂 "Hall of Three Cultures" or "San Wen Tong" in Chinese. The character "Wen" translates into language and culture. The phrase "San Wen Tong" also brings to mind the Hall of the Three Rare Treasures created by Emperor Qianlong as a memorial to three great masterpieces of Chinese calligraphy. The initials of the phrase "San Wen Tong" was reversed and thus turned into "TWS". The last letters "Bi" was added with its literal meaning of "writing instruments". Thus combining the two segments, creating TWSBI.
