Sisu is a salt licorice pastille that was launched in Finland in 1928. For the Finns, the Sisu brand is part of the Finnish spirit that no other brand can replace. Sisulla siitä selviää. (With Sisu, you can do it).

Sisu is a Finnish word loosely translated to mean stoic determination, bravery, guts, resilience, perseverance and hardiness, expressing the historic self-identified Finnish national character.
