The Räsymatto mug is by the Finnish brand Marimekko. The actual mug was designed by Sami Ruotsalainen as part of the Oiva range, but was paired with the classic Räsymatto design by Maija Louekari. The Räsymatto is one of Marimekko’s most famous designs and can be found on a number of Marimekko products. A real classic!
