Aurora Duo Cart Rollerball Pen - Light BlueThe original Duo Cart with the first pen with space to hold a second cartridge while one was installed. Aurora has reinterpreted that iconic pen, creating a new Duo Cart with the typical 50's tapered shape and making it available as a Rollerball. The light blue resin body is complemented by a chrome cap and trims and offset by a black resin grip section. The Light Blue Duo Cart arrives in a black leatherette box with a certificate of authenticity.
