This PRADA Saffiano metal card case in the elusive palladio colorway is a highly functional, minimalist luxury accessory from Pradas classic small leather goods archives.
It is designed explicitly for those who prefer an ultra slim footprint without sacrificing craftsmanship. 
The case is made from Prada's signature calfskin leather which features a heat-stamp crosshatch diagonal pattern and a specialized wax finish.
In Prada's colorwheel, Palladio (named after the chemnical element Palladium) is a distinctive metallic silver-gray tone witha mirror like or brushed luster.
