Using these balloons is a breeze. First, you can choose to inflate them with air using a regular balloon pump or with helium from a helium tank. If you want them to float, use helium. When inflating, don't over - inflate to avoid popping. For storage, keep them in a cool, dry place away from sharp objects. Remember, this listing only includes the balloons, so don't expect other decorations. And if you're using them for an event, plan ahead as helium - inflated balloons will only float for about 12 - 18 hours.
