The tortoiseshell white Souveran pen was produced in 2004, along the lines of the 1950s model 400 pen with tortoiseshell brown/clear ink container. The striped and transparent barrel top shimmers delicately in gold. The cap and the remaining body parts are kept in white and give this model its characteristic bright and friendly shine.
