Description The Pelikan Classic M205 fountain pen in Apatite is a piston filling pen that uses bottled ink only, and features a clear deep teal barrel and cap, with silver trim. The stainless steel nib is a very smooth writer, and does tend to run a bit on the wider side. The Pelikan M205 fountain pen is a mid-sized pen that is comfortable in the hand for most writers. This model is a special edition created to accompany the Pelikan Edelstein Apatite fountain pen ink.
