The 7-year-old girl inside is so jealous of the balloons that are available now. So much better than when I was a child! Foil balloons are made of a very thin metal, and are a lot less porous than regular latex balloons, meaning they will stay afloat for significantly longer. Foil balloons come in all shapes, sizes and characters. You can get love hearts, stars, cars, trucks, animals, Dora and Mickey Mouse. Angels for religious sacraments, Graduation, Engagement, Retirement and farewell balloons. There is even an emoji poop that always gets a laugh.
