Easy filling on-the-go. Ideal for popping in your bag or laptop case, this little fountain pen extends to full length when the cap is posted. The inbuilt vacuum mechanism fills the barrel with a simple up and down of the plunger and helps prevent leakages by creating an internal seal when fully screwed in. Whilst writing, unscrew the mechanism tip to break the seal and allow the ink to flow more freely. The VAC’s demonstrator style transparent body lets you to see the distinctive mechanism within and remaining ink levels, whilst the screw close cap and rubber O-ring create another seal to further stop leakages or drying.
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!
