The ribbon-like threads on these Fulvio Bianconi for Venini Fazzoletto vases are created with the traditional filigrana technique, where glass rods intertwine and wrap around a glass cylinder. The end result is comparable to sheets of lace, which only adds to the whimsicality of the handkerchief-inspired silhouettes. Please note, this item is a truly original vintage piece with slight imperfections and distinctive characteristics that add to its charm and celebrate its unique history.
