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.
TWSBI's belief is that it is important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen. These pens also come packaged with a wrench and silicone grease. Neither of these accessories are intended to be used immediately, as they are for long-term care and maintenance. Additionally, please use extra care if you choose to disassemble the nib and feed, as the feed is very fragile.
If you're taking apart this pen, note that the mechanism on the Vac700R removes out of the pen in a counter-clockwise direction. This is the opposite direction from other TWSBI pens like the 580.
