Vacuum-filler fountain pen from TWSBI


The TWSBI Mini Vac Fountain Pen is perfect for showing off your ink

With no cartridges or converters the TWSBI Mini Vac works using a vacuum pressure system

The TWSBI Mini Vac is a vacuum-filled fountain pen so no cartridges are needed. With vacuum filling systems, the barrel contains a plunger which is pulled back to fill and then, with the nib in the ink bottle, the plunger is pushed down which creates a lower air pressure behind it. As the plunger reaches the slighly wider part of the reservoir, the difference in pressure causes ink to rise in to the barrel and fill it up. Because of the sealed nature of these pens, they are better for travelling than piston fillers as the barrel is sealed from the nib when stored.  This means that for more than a few sentences you need to turn the piston to unlock and release the flow. For a few lines though you can just uncap and go. You can also use the special (and rather beautiful) Mini Vac bottles to easily fill the pens with your choice of ink.

This is the slightly shorter version of the Vac pen with a rounded faceted body and a steel nib. The pen comes in a gift box with a special spanner and silicon grease so that you can disassemble the pen and maintain it your self. A leaflet is provided should you wish to have a go but it should not be necessary for normal use.
