Using these balloons is super easy. First, you can choose to inflate them with air using a balloon pump or with helium from a helium tank. If you want them to float, go for helium. Just attach a string to the balloon once it's inflated to hang it up. Remember, the floating time with helium is about 12 - 18 hours. These balloons are biodegradable, so you don't have to worry about harming the environment. When you're done with the party, you can simply dispose of them properly. Keep them away from sharp objects to avoid popping. Store them in a cool, dry place if you want to use them later. And don't forget, this listing only includes the balloons, so get other decorations separately if you need them.
