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 partially clear 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). 
 
This pen has vibrant shades of blue and light green, perfect for adding a cool, refreshing touch to your collection.
