TWSBI Vac700R Replacement Nib Unit

For the serious writer, the TWSBI (commonly pronounced “twiz-bee”) Vac700R features a high-capacity vacuum-filling system that draws up over 2ml of ink in a simple, one-handed operation.To prevent any unseemly burping or leaking due to air pressure or heat changes in the environment, the shut-off valve keeps ink inside the clear barrel reservoir instead of on your hands. For long writing sessions with consistent ink flow, open up the valve to allow more ink to access the feed. The stainless steel nib writes smoothly without interruption.Unlike other vacuum-filling pens, the Vac700R is meant to be completely taken apart for thorough cleaning. A special wrench and silicone grease are included to aid in the maintenance of the pen.TWSBI Vac700R Fountain Pen Specifications Edition: Standard Pen Material: Transparent Resin Nib Material: Stainless Steel Filling Mechanism: Internal Vacuum-Fill Mechanism (Bottled Ink Only) Pen Length, Closed: 5.79 in. / 147mm Pen Length, Open (Cap Off): 5.28 in. / 134mm Pen Length, Open (Cap Posted): Cannot be posted.
