The smal subtraction bowl can still hold a lot of items
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 box with a cavity shaped like a part of an inflated square carved out of one side. It's the perfect bowl 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).
