Uni is the Japanese word for sea urchin and is one of the most popular delicacies. This interpretation of a sea urchin in cast metal is a feast for the eyes. The mould is first modelled by hand in wax and then used for the casting. These little works of art are handcrafted by extremely experienced artisans. Aluminium vessels should not be filled with water, as the metal can otherwise corrode. When using Uni for cut flowers, a slim plastic insert should always be used. The surface can be cleaned with a soft cloth, a bit of dishwashing liquid and warm water, but sharp and abrasive objects will leave scratches on the delicate finish.
