EXCLUSIVE AT NET-A-PORTER. Naturae Sacra believes "natural forms can be just as artful as modern design, " which is why the curved shape of this 'Ourea' tote is inspired by the Ancient Greek Mountains of the same name. Topped with the brand's signature hand-poured resin handle, it's made from smooth vegetable-tanned leather and sized to fit all your daily essentials, plus a tablet.
