Coral-red Parker Duo Special fountain pen. Push-button filling system. The filling mechanism is not functional; a new rubber sac must be installed before the pen can take up ink and write again. The nib is a Penol brand and therefore not original to this model. There are no defects, but there is a slight color variation between the top and bottom of the barrel (as can be seen in relation to the cap). The factory imprint on the pen has almost completely worn away. Length: 13.3 cm
