An iconic lamp, the Parentesi, is presented for its 50th anniversary in the new turquoise edition. The conception of Parentesi was born from the work of two designers: Achille Castiglioni and Pio Manzù, produced by Flos in 1971. The turquoise color takes up the color used by Castiglioni to paint his house. "The sketch had all the elements to make Castiglioni fall in love: flexibility, ready-made, lightness". The story of Parentesi is special and ingenious.
