The Asakusa bowl with its organic amorpha shape is a small design highlight. It is made by hand from double-walled sheet metal. The inside of the bowl is polished to a high shine and the outside is finished with a dark-grey patina. This bowl may not come in contact with acidic substances, for example fruit that could overripen, as this could leave spots on the patina. It can be cleaned with warm water, dishwashing liquid and a soft cloth.
