This Sweethearts Moomin mug was released same time as the Green Loving Care mug. These are a part of Classics Collection and were released alongside other Moomin items such as plates, bowls, textiles and mini mugs.

On the front side of this pink/purple mug you can see Moomintroll and Snorkmaiden getting along very well. On the other side Snorkmaiden is hitting Moomintroll with her diary. I wonder what caused such an outburst?
