Using these balloons is a breeze. First, decide whether you want to use air or helium to inflate them. If you choose helium, the balloons will float for about 12 - 18 hours, giving a great effect for your event. For air, you can just blow them up or use a balloon pump. When decorating, you can hang them from the ceiling or use them as part of table centerpieces. Remember, this listing only includes the balloons, so don't expect any other decorations. Store the balloons in a cool, dry place when not in use to keep them in good condition. Avoid sharp objects that could pop the balloons, and if they get dirty, you can gently wipe them with a soft, dry cloth.
