Foil balloons (Also known as Mylar Balloons) are balloons made from a durable type of Nylon that is coated with foil. They come in all shapes and sizes ranging from cupcakes, hearts and characters and are popular for their durability and longevity.
Whereas normal latex Balloons last around 12 hours, these balloons will last over a couple of days and sometimes even weeks.
If you are hosting a multiple day event, or simply need balloons that last longer, then these are for you.
