Using these balloons is super easy. First, make sure you have either an air pump or a helium tank. If you're using helium, it's best to use it outdoors or in a well - ventilated area. To inflate the balloons, just attach the nozzle of the pump or tank to the opening of the balloon and gently fill it up. When using helium, the balloons will float for about 12 - 18 hours. For air - filled balloons, they'll stay inflated for a longer time. When it comes to storage, keep the unused balloons in a cool, dry place. Avoid exposing them to sharp objects to prevent them from popping. After use, since they're biodegradable, you can dispose of them in an environmentally friendly way. Remember, this listing only includes the balloons, so don't expect any other decorations.
