To properly use these aluminum F balloons, locate the self-sealing valve and inflate them using an air pump or straw. Take your time while blowing air into the balloons, ensuring a slow and controlled process. For optimal results, charge the pump to 90% before using the straw to blow air.

These balloons are reusable, simply deflate them with a straw after the party ends. When filled with air, our high-quality balloons are unlikely to leak and can last for several months or even half a year. Perfect for various occasions such as weddings, birthdays, bridal showers, baby showers, and anniversaries. Please note that due to the special nature of these balloons, they cannot be opened for inspection. However, rest assured that the damage rate is only 0.5%.
