The TWSBI Vac 700r is a demonstrator fountain pen with a vacuum filler mechanism and a stainless steel nib.

For its comparatively low price, the TWSBI Vac 700r fountain pen still looks stylish. The clear-barrel vacuum filled ink chamber, chromed metal trim and TWSBI logo go towards its distinct look. The final look is completed by a stainless steel nib, available in a variety of sizes are made by the German nib manufacturer, Jowo.

The Vac 700r is an updated version of the Vac 700. The grip/feeder section has been made larger with a more dramatic taper, and its two small valves have been replaced by a single larger valve. Both of these upgrades to the original design have had the end result of increasing the flow. It’s also worth noting that it is these same improvements that have been included within the design of the compact version of the TWSBI Vac 700r.

The TWSBI Vac 700r is a plunger filling fountain pen that can be refilled quickly and simply with one push and release of the plunger. It’s worth noting that ink cartridges cannot be used with a plunger filling fountain pen.

TWSBI have produced pens for other manufacturers for the past 40 years. They decided to make their own in 2009, and the TWSBI project was born. Pens were produced and, harnessing the power of social media, were improved and refined until there is little doubt that outstanding value for money piston and plunger filler pens available today. The pens all now feature nibs from Jowo, our favourite German nib manufacturers, TWSBI have been built with the enthusiast in mind, so each pen comes with a spanned to undo the back of the pen, allowing access to the filling mechanism for cleaning the pen and, of necessary, to allow it to be lubricated with silicon grease, which is provided. This is an option – in general use you won’t need to do this, but the option is there for those who want it!
