S.T. Dupont has collaborated with luxury sportswear maker Casablanca for a series of accessories. The Ligne 2 lighter, cigar humidor and ashtray are adorned with colored lacquer squares, reinterpreting the lines of tennis courts and decorative historic Greek architecture. Slimy, Biggy, accessories, and the Line D Eternity pen are adorned with a metal mosaic guilloche or a mosaic pattern, sometimes enhanced by a layer of transparent lacquer. Casablanca and S.T. Dupont also developed a line of leather goods for this collaboration. A cross-body cigar pouch, document holder, and, in slightly grained leather, a case for two cigars and a case for one pen are highlighted with Casablanca’s primary colors and the white lines borrowed from tennis courts.
