Nambe's products are made of a 'patented metal alloy'. They are a high-end manufacturer and often contract with top designers, hence most of their products are expensive. However, those shakers just sold this morning so are no longer available from us.
What is special about Nambe?
It traces its history no further back than 1951, when a Los Alamos metallurgist discovered a durable new aluminum alloy, which he called Nambe. This alloy, it turned out, is incredibly nonporous, while relatively lightweight and superb at retaining both heat and cold for long periods.
Is Nambe good quality?
