The Line of Marseille is 19.5" long. It is cut in a 1.5mm thick sheet of steel and then finished in black.
Off Frioul islands, from La Joliette to Roucas Blanc, you can admire distinctly Malmousque, Notre Dame de la Garde, and the Gap of Vauban.
It is wrapped up in a nice cardboard box, including 3 black nails of course!
