TWSBI Fountain Pens

TWSBI fountain pens are highly regarded for their innovative piston filling mechanisms that make it quicker and easier to fill the pen with ink. The GO range use a spring which pulls the ink up in an instant as the spring is released. Designed with transparent bodies so you can see the inner workings of the pen, TWSBI supply a toolkit with every pen so you can take it apart and clean thoroughly. The TWSBI ink bottle has an adapter that connects directly to the Diamond range for fuss free filling.
