Using these balloons is a breeze. You can choose to fill them with helium for a floating effect or air for a long - lasting display. If you're using helium, inflate the balloons close to the start of your event to make sure they float throughout. If you're using air, you can inflate them well in advance as they'll stay inflated for 5 - 7 days. Always keep in mind that these balloons pose a choking hazard to children under 8, so keep uninflated or broken balloons away from them and discard broken balloons right away. Adult supervision is a must when using these balloons. There's no special maintenance required, just enjoy their beautiful pastel burgundy color for your party or event.
