Monteverde presents and entirely new approach to a 3 function luxury writing instrument. The MEGA M3 is one single pen that can function as a ballpoint pen at one end with an interchangeable Inkball tip/fountain pen nib at the other. Then InkBall tip is easily substituted with a German fountain pen nib with an Iridium tip. Also included are 12 ink cartridges, 6 super mini ballpoint refills and an extra Inkball front section.
