TWSBI GO

TWSBI GO
 

The TWSBI GO fountain pen is a new pen by the Taiwanese pen factory, with a new filler system.
As so many other TWSBI models, also the GO is a demonstrator fountain pen.
The TWSBI GO is available in 2 colours: Sapphire and Smoke.

The TWSBI GO fountain pen will be fitted with Jowo steel nib in Extra Fine, Fine, Medium, Broad and Stub 1,1mm nibs.

The real innovation is the big spring inside the barrel, which holds the plunger at the top of  the reservoir , that pushing down the plunger allows to refill the pen.
