This Yellow moomin mug by Arabia Finland, was in production 1990-1996.
This mug is in a good used condition without spoonmarks.
There is one thin 3mm scratch that is seen on the second and third pictures (behind the second bird).
At the bottom ring there is a small smooth indentation (see close up picture), that seems to have arisen already at manufacuring, as the glaze seems to follow the border of the indentation.
Condition: Good used condition
