Juanola, the traditional brand of throat lozenges born in Barcelona, forms part of the collective memory of many generations. Its small size and diamond shape, its color –black–, and its distinctive flavor are also the main features of its corporate identity and of a memorable, decades-old packaging design.

Duró contributed to its renewal discreetly restyling the Juanola logo and its packaging by polishing certain graphic elements to focus on the brand.
