Have you ever tried to put a lime into a Corona, and it just wouldn’t fit? Yep. You’re not alone. Introducing Lime Guides. Using UV laser technology, Corona marked limes with a simple guide showing exactly where to cut, helping people cut the perfect slice for their bottle or can. Lime Guides made Corona show up in the fruit aisle for the first time, and flipped the logic of purchase. Now people buy a Corona after seeing a lime, not the other way around.
