In the national competition, the competitor Oulevay from Morges emerged as the winner of the Second World War. Oulevay invested in new facilities, which cost a fortune and nearly cost the Wernli brothers their existence. The new, low-priced "Oulevay Cookies" flooded Switzerland. Ideas were in demand.
During this time, the red Wernli logo was created, which still stands as a guarantee of quality on all packages. Since 1948, this lettering has given the brand its face.
