Supplied flat, not inflated. There are 2 in a pack. Beautiful giant Red balloons. These massive balloons look absolutely amazing in photographs and have a big visual impact. They can be inflated with helium or air. At 3ft across they are very striking and use a whole disposable canister of helium to inflate. One canister for 30 x 9inch balloons will inflate on giant balloon, purchase these from a supermarket or large toy outlet. To inflate to the right size place two dining chairs back to back exactly 3ft apart (or however large you wish to go). Inflate the balloon until it just passes between them. This way all your balloons will be the same size. Inflate indoors - you wouldn't want the balloon to escape, and tie firmly with balloon ribbon. The balloon is able to carry decorative ribbons and tassels as it is so large.
