Penna stilografica FRICTION PENNINO PELIKAN M400 VERDE STRIATO - PRIMA variante - pennino OM 14k
This is a much rarer pen than most M400's. Another unusual feature of this particular pen is the nib. Most of the M400 nibs had a little bit of flex. This pens has the most flex I have ever experienced from a 1970's and later Pelikan.
