Ad agency JWT designed the Grater Card for cheese shop Bon Vivant.

How do you reinforce a brand to clients and customers? For ad agency JWT Brazil, one way was to create a business card that people can actually use with your product.

JWT designed a business card that doubles as a mini grater for Bon Vivant, a Brazilian shop specializing in cheese. Dubbed as the Grater Card, the business card is made of a light metal. It comes with a protective sleeve and can grate all kinds of cheese.

The Grater Card became such a hit with customers that the cheese shop had to create a rule that customers have to wait two to three days before they can get another card.
