TWSBI VAC Mini Fountain Pen - Clear - Extra-Fine
TWSBI's Vac700R utilizes a vacuum filling system. Merging this time-tested, yet somewhat rare, mechanism with TWSBI's notable industrial design yields a truly unique fountain pen that holds almost 2.5ml of ink! The crystal clear body allows for an unobstructed view of the ink level in the barrel, and a #6 stainless steel nib provides a smooth writing experience. The clear cap is threaded and should not be posted, and includes a silver clip.
TWSBI Vac700R Fountain Pen - Clear - Fine
The TWSBI Vac Mini is a slightly shorter version of the Vac700R. This clear demonstrator fountain pen fills via a vacuum filler mechanism, has translucent grey accents on the grip and piston knob, and has a stainless steel nib. 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.
