The blown glass is handcrafted using traditional balloton work with a metal mold for a cross-relief effect.

"It looks soft, yet it is glass. The optical illusion of VENINI's 1970 Monofiori is in its name: Balloton, the unique workmanship that recreates the matelassé effect on the surface. The piece is handcrafted, blown in the distinctive metal mold and finished in the slender neck with a heat-applied colored thread that varies in color."
