Description The Pelikan Souveran M600 Green and Black fountain pen is a piston filling pen that uses bottled ink only, and features a body of green and black striped celluloid acetate, with a black cap and gold plated trim. The 14k bi-color gold nib is a very smooth writer, and does tend to run a bit on the wider side. The Pelikan M600 fountain pen is a mid-sized pen that is comfortable in the hand, but not too large for most writers.
