To understand the true value of a Pelikan, you have to understand its internal
writing system. By inventing the differential piston filled ink system for the fountain pen, filling is clean and easy while still guaranteeing a steady
inkflow. The 14kt gold nib of the 400 fountain pen is engineered to within 1/1000 of an inch. The 400 ballpen and 0.7mm pencil have easy one handed push
button mechanisms while the roller refill is the smoothest in its class.
