No Helium required! Simply inflate the Airloonz with an air pump following the included directions. Assemble on the base and you will have an instant centerpiece. Great for taking selfies with the favorite Bluey and Bingo Characters. Bluey and Bingo measures 49" tall when fully inflated and is designed to be inflated with air only. No expensive Helium is 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. The 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. No air compressors as the air is too fast! 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 air from escaping after it's inflated. Balloon arrives un-inflated.
