Like the shape of some shells, the shape of galaxies and the arrangement of the leaves of some plants, Guilloche Torchon with its spiral in an elegant verdigris color reflects the perfection of nature.  The fountain pen features an integrated piston with 1.5ml capacity, designed and produced in Leonardo's Italian workshops.
