If you want a piston filler with a metal body then look no further.
Aluminium barrel and grip with stainless steel trim and pocket clip. TWSBI logo nicely finishes the top of the pen's cap. Rubber o-ring on cap thread ensures an airtight seal to prevent ink drying out in the pen, whilst also ensuring that the cap is firmly attached to the pen when not in use.
Diamond-faceted barrel ensures pen will not roll away if left uncapped on a desk. The barrel and nib section has a slightly textured finish to aid grip. The piston mechanism is smooth and very satisfying to use. The pen holds a good amount of ink and there’s a small ink window so you can see how much ink is left
Being a piston filler means it has the filing mechanism built into the body of the pen - simply dip the nib into a bottle of ink and turn the screw on the base of the pen and the ink chamber will fill up with ink.
With nibs sized from extra-fine to 1.1mm stub there is a Twsbi to suit every style of writing. If you're looking for smooth writing sensation we would recommend the medium nib or broader.
It uses a rubber o-ring on the cap thread to ensure an airtight seal to prevent ink drying out in the pen, whilst also ensuring that the cap is firmly attached to the pen when not in use.
