The Simone Rainer brand reinforces the idea of cohesion between two distant worlds: that of the traditional and handcrafted "made in Italy" leather industry and that of abstract geometry. A handbag collection developed from numerical studies related to a unique proportion: the golden ratio. The result is a concrete and aesthetic progression of mathematical proportions, innate in nature and well-established in the western aesthetics, synonyms of beauty and perfection. These are the key elements chosen by Simone Rainer to establish in 2011 his brand, conceptually conceived to marry preciousness with a tactile experience. The obession for the shapes of triangles, pentagons and circles, enclosed in the logo, push the product towards an iconic design.
