Posting magnets is a modern take on sticker tagging -one of the first urban art forms. We have been posting magnets professionally since the beginning. Advertising magnets are highly target-able and can be placed exactly where your young customers are. Considered a lifestyle marketing tactic, we place them alone or in groups and sometimes we will hand write messages on the magnets to delver a more personal message. Sticker tagging is great for all kinds of clients. I would use stickers in locations where I know that my target is all the time such as a bar, skate shop, or music venue. Advertising magnets are keepsakes for your fans who take them home to commorate the event. They rock.
