After 50 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 50 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 is one of the most loved modern pen brand!
