How to inflate and deflate these balloons

Each balloon has a self-sealing valve. Use the included straw or a hand pump to inflate with air or helium. Fill to about 90% capacity—overfilling may cause popping. To deflate, insert the straw into the inflation hole to release air. The self-sealing design helps keep the balloons from leaking for nearly a week.

Balloon set details at a glance

Are these balloons reusable?

Yes. Thanks to the self-sealing valves, you can deflate the balloons with the straw and reuse them for another celebration. Just handle them gently to avoid tears.

Can I use helium?

Yes, these foil balloons work with both air and helium. Helium makes them float, while air keeps them in place for easy hanging.

How to avoid popping the balloons?

Inflate only to about 90% of full capacity. Overfilling can cause the balloons to burst, especially in warm conditions. The self-sealing valve will hold air well at the recommended fill level.

Decorating ideas

Create a custom banner by arranging the letter balloons on a string or directly on a wall. The blue color works well for beach, ocean, or gender-neutral themes. Hang them in a kitchen, living room, or party area to make the birthday person feel special.
