One of the oldest and most elaborate collections of the Tondo Doni line, Metropolis, is composed of pure crystal with 24% PbO, made entirely by artisans, through the technique of blowing and grinding by hand. Representing cosmopolitan design, Metropolis is the collection that most expresses a conceptual and minimal aesthetic. Metropolis is born from the ambitions of growth and maturation of the activity. Suspended between cubism and modernism, the vases in this collection are made in limited edition of 500 numbered pieces.
