Arabia Moomin mug Moominvalley was made in collaboration with Moomin Museum, that was opened in Tampere, Finland. The mug has a special stamp with Moomintroll looking over his shoulder on the bottom. 

Tove Jansson had donated a  collection to Tampere art Museum in 1986. At first this Moomin mug was only sold at the Moomin shop next to the Museum. After May 2017 other retailers could start selling the mug as well until it was sold out later that year.

The mug was sold with similarly themed cardboard box.
