This latest gray Arabia's Fillyjonk Moomin mug is designed by Arabia's illustrator-ceramicist Tove Slotte, based on Tove Jansson's book The Moominvalley in November (1970) and the comic Fuddler's Courtship (1959). As seen in the illustrations for the set, Mrs. Fillyjonk has the uncanny ability to find any spots where dust or dirt might be hiding and, once uncovered, attacks the problem with a torrent of soapsuds. Also see the Fillyjonk bowl and plate of the same collection.
