Add a touch of whimsy and excitement to your event with our vibrant 40-inch teal blue number balloon! But wait, there's more! Let us guide you on how to properly handle our aluminum F balloons for maximum enjoyment. Step one: locate the self-sealing valve. Step two: inflate with an air pump or straw, taking care to go slow and not overinflate. We recommend using the pump up to 90% capacity before switching to the straw for better control. Remember, if you encounter a sticky situation with two layers of aluminum F, pause the inflation process, separate the layers, and then continue. Step three: these balloons are reusable! Just insert a thin tube into the charging opening, release the gas gently by pressing the balloon, and fold it up for future use. With proper care, our balloons can last for months or even half a year! However, please avoid exposing them to extreme heat as they may burst. Due to the unique nature of our balloons, we are unable to open them for inspection. Rest assured, our damage rate is only 0.5%. In case of an urgent situation, a temporary fix can be made by using tape to cover any holes. So go ahead, let the fun begin!
