The Cassero collection designed by Patricia Urquiola for Serralunga is inspired by the molds that are used in the construction industry when building with concrete. This Collection of one-piece vases made in polyethylene deliberately have a cement effect as if they had been cast and then extracted from a mould. With the Cassero colleciton, architect Urquiola has chosen to create vases that are not only perfect for outdoors, but also to bring plants into interiors, and has included them in the world of decor.
