For the final, most pleasurable, part of the coffeemake's ritual: a set of four espresso cups, engineered to be elegantly stackable, easily storable and beautiful to look at. Each comprises a polished steel interior with a gleaming copper finish. The perfect cup to start a day or end a meal. The cups are double-walled. The volume of each cup is 50ml. Not dish-washer safe. Wash in warm soapy water and dry thoroughly with a soft cloth.
