A "Union" was set up in 1902 when a number of Haarlem confectioners started up their own chocolate factory in an old convent which still houses the Union Edel company today. Later, they became part of the world famous Neuhaus Group, specialising in the production of napolitans but at the end of 2004 a management buy-out saw the foundation of a new company, Union Edel. Since then innovative product development has meant that the simple napolitan has become a stylishly packaged creation with striking and contemporary wrapper designs.
