When you wrap a gift in fancy paper, the last thing you want is ugly pieces of tape stuck all over it. That's why 3M created its Scotch-brand tape that's nearly invisible, and a selling point that Hamburg-based ad agency Kolle Rebbe perfectly drove home with this clever packaging for the product that looks like a completely empty box.
In reality, when the top of the box is opened, there's actually five replacement rolls of tape inside that are cleverly hidden by a thin angled mirror. It's an old trick we've certainly all seen before but re-purposed perfectly here. And the packaging earned Kolle Rebbe a much deserved 2014 CLIO award, which is like the Oscar for advertising.
