Using these balloons is a breeze. First, get your air pump or helium tank ready. If you're using helium, it's best to have someone help you so the balloons don't float away while you're tying them. Simply insert the nozzle of the pump or tank into the balloon opening and start filling. Tie a knot at the end when it's the right size. Remember, this listing only includes the balloons, so don't expect any other decorations. When it comes to maintenance, keep the balloons away from sharp objects to avoid popping. If you're not using them right away, store them in a cool, dry place. After the party, since they're biodegradable, you can dispose of them in an environmentally - friendly way.
