This was a project for Uni, when I was still living in Brazil.
Our task was to choose a product that we thought deserved some improvement package-wise.
The subject chosen was a milk carton for the Mu-Mu brand.
In order to help children to associate where the milk that is in their refrigerator comes from.
The classic cow patter was the chosen one, as well as a carton with a square base so its easier for children to have a tighter grip on it (in Brazil most milk is UHT and comes in 1L cartons with rectangular base).
The result was very appealing for the consumer and should it make it easier for parents to convince children to drink milk out of such an adorable container (parents have a hard time convincing their children to drink milk in Brazil, its harder than to convince them to eat fruits and vegetables).
