TWSBI Kai Fountain Pen

The TWSBI Kai fountain pen sits uniquely within TWSBI's range, with its classic design featuring a marbleised royal blue/black resin, with contrasting gold-plated trim. The nib is TWSBI's signature #5 size (like the Diamond 580 models) and is also gold-plated. It comes available in a range of nib widths, from EF to B. It measures 14.1cm in length capped, and weighs 31g.

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.
