Using these balloons is easy. First, decide if you want to use air or helium for inflation. If using a helium tank, make sure it's properly set up. Just insert the nozzle into the balloon opening and fill it up. If you're using air, you can either blow it up by mouth or use a hand pump. For helium - inflated balloons, they'll float and add a great touch to your party. Keep in mind that the floating time is about 12 - 18 hours. When it comes to storage, keep the balloons in a cool, dry place. If they get dirty, you can gently wipe them with a soft, dry cloth. Remember, this listing only includes the balloons, so don't expect any other decorations. Enjoy using these balloons to make your special events even more memorable!
