TWSBI may be a new name in pens, but the company has a history of over 40 years of manufacturing, including making high-end pens for other brands. Their range is targeted at pen and pencil enthusiasts, and includes fountain pens with the sort of innovative filling mechanisms rarely seen these days, and the kind of all-metal drafting pencils that almost became extinct with the rise of CAD. Many models feature crystal-clear or colour-tinted barrels, so you can really appreciate the inner workings of your new writing instrument. TWSBI is the brand name adopted by TaShin Precision. Why 'TWSBI'? TWS is the reversed initials of the phrase 'Sen Wen Tong' (or Hall of Three Cultures) , plus 'BI' - literally writing instrument. How do you say it? 'Twiz-Bee'!
