The TWSBI Vac700 fountain pen combines bold demonstrator styling with an innovative vacuum filling system designed for impressive ink capacity and smooth, consistent performance. With its clear barrel and substantial size, the Vac700 showcases both your ink and the fascinating mechanics inside, making it a standout choice for everyday writing or desk use.
Filling the pen is simple: just pull the plunger up, push it down, and the vacuum mechanism quickly draws ink into the barrel. The Vac700 now features even more consistent ink flow when the valve is opened, ensuring a reliable writing experience across long sessions.
An integrated ink shut-off valve allows you to seal the ink chamber for safe transport, helping prevent leaks and making the pen easy to carry without worry.
There is not one pen that has the same exact color accent as another; every pen will be similar in color accents but all slightly different due to the nature of this finish.
