Yes! These aluminum foil letter balloons can be inflated with either air or helium. When filled with helium, they will float freely, making them great for floating balloon displays. When inflated with air, use a straw or hand pump and prop them up or attach them to a surface for your backdrop.

How long do the aluminum foil letter balloons stay inflated?

Thanks to the premium aluminium foil material, these balloons typically stay fully inflated for several days to a week or more when filled with air, and around 1–3 days when filled with helium, depending on conditions. They hold air significantly longer than standard latex balloons.

Are these balloons reusable?

Yes! After your party, carefully deflate the balloons using a straw or by gently pressing the air valve. Fold them flat and store in a cool, dry place. They can be re-inflated for future celebrations, making them a great value for multiple events.
