Rapid, simple filling using an innovative spring loaded piston. The TWSBI GO’s demonstrator style transparent body allows you to see the distinctive mechanism and remaining ink levels. To use, unscrew the barrel, place the nib into your favourite ink and push down on the piston; the spring will quickly push the piston back up speeding up both filling and cleaning time. The lightweight plastic barrel has been faceted to stop the pen from rolling off the table and in the absence of the traditional pocket clip, a small loop is provided to attach your pen to a key ring or lanyard. An ingenious piston fill fountain pen at a budget conscious price.

All TWSBI fountain pens can be disassembled for cleaning and maintenance. TWSBI includes the tools to do so, but recommend this is only carried out by experienced fountain pen users. This should only be carried out as part of long term servicing of the pen; it will not need to be done straight away. All disassembly is carried out at the owners risk!
