Description The TWSBI Vac 700 fountain pens and nib units have been modified and updated, and are now available as the TWSBI Vac700R. This TWSBI stainless steel Broad point replacement nib will fit only the new Vac700R fountain pen, and will NOT fit the older Vac 700 pens. If you own an older Vac 700 fountain pen, then the older style Vac 700 replacement nibs will fit your pen. To swap out your nib, simply unscrew the section, push out the old nib unit and insert the new one.
