Optimize opportunities With an Aurora Optima piston-fill fountain pen you demonstrate the ability to optimize all the opportunities coming your way. A particularly iridescent opportunity is the grey neroperla finish. Red and blue auroloide resin models also shine with the same gleaming silver colored trim. The respected Aurora 14k gold nib is available in extra fine, fine, medium or broad. Be sure to order a few bottles of your favorite ink as this piston fill system makes it easy to reload.
