TWSBI’s roots can be traced back to 1969, with the establishment of Ta Shin Precision in Taiwan. Having spent 50 years as an OEM manufacturer for numerous global companies, in 2009, they decided to launch their own brand of fountain pen – TWSBI. Ever since, their products have gained immeasurable popularity, thanks to their blend of scientific precision with modern flair. Their various ranges always prove a hit with customers, with the brand regularly seeking feedback from users prior to developing their next release.
