The Nahvalur Original Black fountain pen. 
From the depths of imagination surface a new breed of writing instrument tapping into the stream of consciousness with artistic beauty and elegance. Yes, the Narwhal fountain pen is a real pen! The Narwhal drinks deep of fountain pen ink with an internal piston-filling mechanism. The stainless steel fine writing nib has a consistent flow to keep up with an ocean of thoughts.
 
The Narwhal Original demonstrator has a clarity to allow the writer to see the piston-filling mechanism operate and the ink slosh around in the barrel reservoir. The transparent resin is complemented with an art deco chrome clip and engraved barrel band.
