Using these balloons is super easy. First, if you want them to float, use helium; for non - floating balloons, air will do just fine. When inflating, don't over - inflate to avoid popping. These balloons are shipped flat, so unfold them gently before inflation. If you're using them for a party, inflate them a day or two in advance if using air, but if using helium, inflate closer to the event time as they'll only float for 12 - 18 hours. After the party, since they're biodegradable, you can dispose of them in an environmentally friendly way. Keep them away from sharp objects to prevent punctures, and store them in a cool, dry place when not in use.
