Using these balloons is easy! First, you can choose to inflate them with air using a balloon pump or with helium from a helium tank. If you use helium, the balloons will float for about 12 - 18 hours, adding a nice touch to your party. When you're done with the party, just deflate the balloons. Since they are made of biodegradable latex, you can dispose of them without worrying too much about the environment. Keep the balloons away from sharp objects to avoid punctures. Also, store them in a cool and dry place when not in use to maintain their quality.
