TWSBI Go Fountain Pen
The newest offering from TWSBI is this fun and portable fountain pen offered in both sapphire (blue) and smoke (black). Most unique to the Go is the new filling mechanism. Unscrew the plastic cover on the handle to expose the plunger. Then simply place the nib in ink and push down on the plunger. When the springs push the plunger back up, the ink reservoir will fill with ink and you’ll be ready to go!
Available in nib sizes: EF, F, M, B, and Stub 1.1
