Take a plunge with the vacuum-filling Nahvalur (formerly known as Narwhal) Original PLUS fountain pen. This design is a fresh take on the classic demonstrator fountain pen with an upgrade in ink capacity thanks to the easy-to-use vacuum mechanism.

The Original PLUS has a translucent acrylic body so the writer may see the ink slosh around the inside of the pen. Fill the barrel with ink using the vacuum plunger with a simple, one-handed operation. Write smoothly in a variety of stainless steel nibs sizes (number 6 size, manufactured by Nahvalur).

The Azureus Blue acrylic has a clear base with whirls of cool blue throughout the cap and body. The calm blue color is complemented with silver clip, cap band, and appointments.
