18 inch Happy Birthday Butterflies foil balloons. Both sides of the product feature a lilac background with butterflies and flowers, and in the center the phrase "happy birthday".
These balloons are made with mylar film. mylar is a polyester material that makes these articles very resistant.
If kept safe, they may be reused many times.
They can be inflated with helium gas or just air (using a pump). They are also equipped with a self-locking valve that prevents the escape of gas (air or helium) once inflated. As a precaution, we still recommend closing the gas intake by tying a knot with a ribbon or by using one of our professional closures.
In the accessories section, you can find helium disposable cylinders or air pumps.
mylar balloons can and should be recycled in order to safeguard the environment.
Attention: The listed inflation sizes, lift ability, and gas capacity are conservative averages.
