In a partnership with Japan Post, Nestlé Kit Kat and advertising agency JWT have come up with a clever and innovative concept: the Kit Kat postcards!

As the name suggests, these are small boxes of Kit Kat, that can be mailed as if they were a postcard. The product launch was timed with the university exams season, so that friends and relatives could wish students good luck in their studies with a chocolate break :)

Here's the product presentation:

The Kit Kat postcards won the Media Grand Prix this year at the Cannes Lions International Advertising Festival, so we wonder... how long until it is available at other postal services around the world? *hint hint* :)
