AirLoonz are the perfect balloon decoration to highlight your colorful birthday party! This Birthday Cake AirLoonz balloon stands 53″ high when fully inflated and is designed to be inflated with air only. No helium required! AirLoonz balloons include a color matching set of foil mylar balloons that creates a sturdy base for the main balloon to rest on and stand upright. Each AirLoonz has 2 inflation points. One in the top part of the balloon and one in the base. AirLoonz can be inflated with a balloon air inflator or a hand pump. Easy to place elastic strap included. Use a balloon weight or any household item, like a can of soup, in the base to stabilize. Balloon includes self-sealing valves, preventing the gas from escaping after it’s inflated.
