Blue Fluted Mega Thermal Mug 39 cl from Royal Copenhagen combines tradition and modernity with a pattern created by Karen Kjældgård-Larsen in 2000. The hand-painted details preserve the vivid blue effect. This pattern marked the start of a new era in Danish design and represents both historical authenticity and creative innovation. Originally there were eight different designs, and each thermos has a number on the back indicating which design it has. This thermos mug is both practical and a work of art in itself, perfect for everyday moments as well as for festive occasions.
