Guylian’s interactive packaging design competition is aimed at finding the best packaging idea for its Sea Shell Chocolates. The microsite www.whiteboxcontest.com has been launched as a hub where users can register to join the competition and present their design idea. Participants and visitors to the site will be able to share their opinions on the submitted designs and vote for their favourite. For the first time ever, Guylian invites consumers, chocolate lovers and fans to create a new look and feel for the packaging of their hero product, Guylian Sea Shells. Guylian is challenging professional & amateur designers and Guylian fans to create innovative designs from a consumer perspective.
