ThinkCling is a patented cling material that can be used for guerilla marketing, direct marketing, and in-store activations. It clings to surfaces like wood, glass, metal, and brick without leaving adhesive residue. Major brands like Adidas, Nokia, and Vodafone have used ThinkCling for creative global campaigns. An example campaign for O2 used graffiti-style ThinkCling doodles on street furniture to match an online and in-store promotion targeting mobile adults aged 18-34. ThinkCling was also used multiple times in stores as point-of-sale displays.
