With an eye for details, these mugs from Royal Copenhagen are hand painted with a pretty border in the brand's signature color which is called cobalt zinc silicate. During the 19th century, this color was obtained from the Norwegian company "Blaafarveværket", and it is this intensity in color Royal Copenhagen's porcelain is famous for. The princess collection is a classic set both for dinner and coffee and can be matched together with other collections from Royal Copenhagen.
