Pelikan M800 fountain pens are large piston-filling pens with an 18K gold nib. The Souverän M800 is a fairly large pen. It posts securely and the brass piston mechanism adds just the right amount of heft, creating a wonderful balance. The Pelikan Souverän 800 Black fountain pen is a timeless classic. The Pelikan M800 Black with Gold Trim is recognized as the classic “gold standard” for the M800 line of fountain pens. With its black resin body and warm gold on the clip and ring bands, this fountain pen is elegant yet simple, making it a versatile choice for writing. The black barrel is made of cellulose acetate in an elaborate process and has a 24K gold plated ring and clip. The Pelikan Souveran collection is available in 4 shades - Blue, Red, Green and Black and two trim options - Gold plated trims (M800) and Palladium plated trims (M805).
