The TWSBI GO is the most affordable TWSBI fountain pen yet! A unique feature of this model is the spring loaded piston. This resin pen has a clear body and clear grip section, so you can see your ink and the spring piston mechanism at work, and has a clipless push/snap cap. It is completed with a silver stainless steel nib.

It is incredibly easy to fill this pen from bottled ink – simply unscrew the barrel to access the plunger, submerge the pens nib down into the ink, press down on the piston to compress the spring, and it will fill the barrel with ink! Screw the barrel back on and youre ready to write.
