The Pelikan Souveran M800 fountain pen in black is a piston filling pen that uses bottled ink only, and features a body of black celluloid acetate, with a black cap and gold plated trim. The 18k bi-color gold nib is a very smooth writer, and does tend to run a bit on the wider side. The Pelikan M800 fountain pen is the second largest of the Souveran series pens.
