TWSBI GO Clear Fountain pen

The TWSBI GO fountain pen is a radical new departure for TWSBI, with a completely new filler system. Like so many of TWSBI's superb pens, the TWSBI GO fountain pen is a demonstrator, allowing one to see the inner workings - and what unusual workings they are! The ink reservoir is inside part of the section as well as the barrel (rather than being the barrel itself), which needs to be unscrewed to fill the pen. The obvious innovation is the spring that is also inside the barrel, which holds the plunger at the top of the reservoir - unscrew the barrel, place the nib in the ink bottle, push down the plunger, and the spring does the rest. If you have a look at TWSBI's video, below, it's really quite spectacular. Another difference from previous pens from this manufacturer is the cap - whereas TWSBI's pens have always been screw-fitted, the cap on the TWSBI GO fountain pen is push-on.

The TWSBI GO Fountain pen has a polished stainless steel nib engraved with the TWSBI logo, available in several sizes, made by JOWO

With a history of more than 40 years of manufacturing, including producing high-end pens for other brands, Ta Shin Precision decided to start selling under their own brand, TWSBI. The name TWSBI is made up from TWS and BI. ‘TWS’ is the reversed initials of the phrase ‘San Wen Tong’, translated Hall of Three Cultures, and ‘BI’ literally means writing instrument.
