Our U.S Army Hot Air Balloons are made with quality weather-resistant polyester. The Balloon measures 16″ x 12″ with a 26″ attached Curlie tail. The colorful printed panels are backed with plastic and supported by fiberglass rods to maintain the balloon shape. Heavy-duty swivels attach the spinner tail and the hook for hanging. Balloons ship flat and are easy to assemble with included directions.
