Using these balloons is super easy. For helium, just take them to a helium - filling station or use a helium tank at home. Make sure to inflate them close to your event time so they float for about 10 - 12 hours. If you're using air, you can blow them up by mouth or use an air pump. Air - filled balloons won't float but will last 5 - 7 days. Now, the important stuff. Keep uninflated or broken balloons far from kids under 8 because they're a choking hazard. If a balloon breaks, throw it away right away. Always have an adult around when dealing with these balloons. Also, you don't have to worry about the environment as these balloons are non - toxic and eco - friendly. You can use them for all sorts of events like weddings, birthday parties, and more to make your celebration even better!
