The TWSBI Vac 700 ‘s introduction a few years ago was met with both excitement and frustration. I remember Fountain Pen Network being extremely excited by the prospect of a value priced vacuum filler, but the initial release had problems with the nib and feed resulting in many Vac 700s writing extremely dry. The clear demonstrator Vac 700 was delayed for several months while TWSBI worked out the kinks. I finally got around to purchasing the Vac 700 after the major price drop last year.
The Vac 700 boasts a vacuum filler system and a monstrous ink capacity of 1.5 ml. The pen is available in clear, smoke, sapphire, and amber plastics with black accents. The nibs are German made nibs from JoWo and are available from Western EF up to 1.5mm stub. The nib size is a standard #6.
