This fountain pen is made of one of the most prized species of African mahogany called pomelle sapele. This highly figured wood is one of the finest woods in the world. I have just found a piece rated AAAA, which is the highest grade wood can receive. Wood with this much grain figure is incredibly rare. This fountain pen is perfect for collectors. Should you decide to upgrade the nib to solid 18 gold, please ad the nib at the bottom of the page to your order. Style also available in Rollerball.
