Optima Nero Perla. Since its introduction in the 1930's, the Optima has been one of the signature pen models of the Aurora brand. Featuring a flat-top design that distinguishes it from the similar Aurora 88, the Optima, whether in high quality resin or upscale Auroloide celluloid, features a generous and reliable piston-filler system and Aurora's smooth-writing 14k nib units. Shown here in the Nero Perla, a beautiful palette of pearlescent greys. Our price $476.
