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.
