Blue Fluted Mega thermal mug from Royal Copehagen. Warm yourself with a hot cup of tea or coffee. Blue Fluted Mega is a new interpretation of Blue Fluted Plain - The mussel-painted pattern from 1775, which became part of Denmark's cultural heritage. In Mega, selected parts of the original pattern have been enlarged by Karen Kjælgård-Larsen. Each part of the series is unique and hand-painted, just like Blue Fluted Plain.
