Cylinder Capacity 

Large Balloon Displays: Please note for larger quantities of balloons it may far more cost effective to rent a helium canister rather than buy a smaller disposable one (disposable canisters have a far smaller capacity than rented ones, rented canisters can hold up to 20x as much gas). Rented helium canisters are widely available on line (we do not currently supply this service)
