Using these balloons is a breeze. First, decide if you want to use air or helium. If you choose helium, the balloons will float for around 12 - 18 hours, which is perfect for your party. Just make sure to inflate them carefully to avoid popping. Since the balloons come flat, you'll need to inflate them yourself. When it comes to storage, keep them in a cool, dry place away from sharp objects. And remember, this listing is only for the balloons, so don't expect any other decorations. Enjoy using these eco - friendly balloons at your next event!
