L3 is a washbasin made of robot-worked and hand-finished Lecce stone.‎ The washbasin was made using a robot, finished by hand and subsequently treated with particular mixtures of resins to make it waterproof.‎ The color is beige and may have small veins of color, which differ from washbasin to washbasin as they depend on the extraction point and the chemical composition of the stone.‎
