The medium sized subtraction bowl has a 16 cm diameter
A hole in a box, a solid and a hollow part, the convexity and concavity of a hold-all container. In an elegant glossy finish, this interpretation of the classic theme of opposites, positive and negative, is a low cylinder with a cavity shaped like a part of a sphere carved out of one side. It's the perfect bowl or fruit basket, with a purpose that can change according to the need of the moment.
All Substraction bowls are sized according to Fibonacci sequence (it is the closest approximation in integers to the logarithmic spiral series).
