Arabia Moomin mug Keep Waters Clean was part of the Swedish “Keep Sweden Tidy” campaign. The campaign was about saving the Baltic Sea. Keep Waters Clean is also sometimes called “HSR” because the Swedish name of the foundation is “Håll Sverige Rent”. This cooperation was a great match since the sea and nature were very important to Tove Jansson. 

The mug was sold in Sweden and exclusively at Moomin shops in Helsinki, Finland and in the moomin.com online store.
