The shape you do not expect from the Otta handle: an octagonal section, with the appearance of an industrial tool. By touching the hand, a “sharp” sensation is expected. On the contrary, the touch gives us surprising softness and sinuosity. Otta was born from an industrial inspiration developed by architect Roberto Rocchi starting from the simple sketch of an octagon that inspired the shape and name of the series.
