ThinkCling is a patented cling material that can adhere to surfaces like wood, glass, metal, and brick without leaving adhesive residue when removed. It allows for creative guerilla, direct, and in-store marketing campaigns. Major brands like Adidas, Nokia, and Vodafone have used ThinkCling for global campaigns. Boots used ThinkCling in window displays and in-store wall cladding printed on clear and white material for a Christmas promotion.
