685TaG Submarine Fountain Pen is truly a one of a kind product. Their slogan is "Dive Into The Timeless Flow" and the brass construction shape of the pen is inspired by Submarines.
The BioFiber grip ensures a stable, free flowing writing experience. The Turbo-Filling System makes filling the pen with ink a breeze. Once you put the plated nib inside the ink, twist the knob and the ink inside the pen will refill kind of like the submarine's turbine system. I love the feel when writing with this pen and it keeps me inspired and creative with my work.ClipsScience & Tech
