Sailors Ahoy! Moomin Sailors is a collection with a nautical white and blue colour theme spiced with some lovely Moomin details. Tove Jansson loved the sea - and that is why sea has such an important role in her Moomin stories and illustrations. Muurla’s enamelware consists of a carbon steel core that carries a double-coating of enamel. The lid of the jar is made of natural cork.
