TWSBI - Inspired by writing


After 40 plus years as an OEM manufacturer for different global brands, Ta Shin Precision decided to start selling under their own brand, and thus TWSBI was born.


TaShin Precision has over 40 years of experience in manufacturing with plastics and metals. Early products ranged from toy lego parts to high end writing instruments. This knowledge trickles down into every product TWSBI has to offer.


TWSBI's name stands for the phrase "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.
