In 2016 the Ink of the Year Aquamarine is exquisite, serene and full of power. The color is neither blue or green but somewhere in between. Name was chosen by Facebook fans. For those who love to write with the extra smooth Edelstein Ink but prefer to use a cartridge Pelikan offers elegant metal cases filled with 6 large capacity cartridges. Every single cartridge is decorated with the Edelstein Ink logo. To complete the oh la la-effect Pelikan has developed an extraordinary packaging: The boxes with their high-value embossing offer an elegant home to the cartridges which are nestled into a small piece of soft tissue paper. These small boxes not only slip easily into the pocket of your jacket but also make a perfect gift for all kinds of occasions to accompany a thank you note to welcome guests at a party to treat yourself to a little something after completing a difficult task . . . and more!These giant ink cartridges fit into every Pelikan Cartridge fountain pen (as they have exactly the same shape as the 4001 giant ink cartridges).
