Your Aurora fountain pen can be refilled with Aurora ink cartridges, or an Aurora ink converter and any brand of bottled ink. Aurora ink cartridges are offered in blue or black ink. If you opt to refill with an ink converter, there is a rainbow of ink colors from which to choose. Colorado Pen offers a huge 90ml bottle in ten different colors. Pelikan's premium Edelstein arrives in a stunning bottle containing smooth writing, vibrant ink. Customers' favorite colors in the standard Pelikan and Waterman brands are an option as well.
