This silver stainless steel replacement nib unit fits the TWSBI Vac700R. It includes the nib, feed, housing, and clear grip section.

The Vac700 has been updated to now be called the Vac700R. TWSBI made small updates to the internal of the pen valving. The old Vac700 used to have 2 small valves. Now, it has only 1 large valve. The bottom of the grip/feeder section has also been enlarged and tapered more drastically. They found by doing these two adjustments, the flow of the pen when the end cap is open increased a small percentage. This is the same design they incorporated in the Vac Mini series.

Due to the bottom of the grip/feeder section being enlarged and tapered differently, the individual nib sets from the original Vac700 pen will NOT work on the Vac700R. Only the Vac700R nib sets will go along with the Vac700R fountain pen.
