Coca-Cola new grip bottle printed on Velcro

Let people know about how the Coca-Cola Grip Bottle has a better grip for holding.
Posters printed on Velcro were placed in bus shelters in Paris to make people interact with the grip.
People literally hooked to the campaign.

I love how it captures the attention of the people at the bus stop.
It forces the user to get involved with the advert but in an interestingly unique manner.
