Black Foil Number '9' Balloon
Cool black foil number NINE balloon, perfect for a 9th birthday party!
Inflate with air or helium
PLEASE NOTE: these balloons do not come inflated, you can fill these with helium a couple of days before your event as they last almost a week or longer. The measurements above are prior to inflation. Balloons become 3D and smaller as they are filled.
*Foil balloons are sensitive to extreme temperature changes. In cold air they may appear deflated; warm air should expand them again. Extreme heat could cause the helium to expand and burst the balloon.
Foil Balloons may conduct electricity. Do not release helium filled foil balloons outdoors or near overhead power lines. Use a non-metallic ribbon and attach the balloon to a weight to keep from floating away.
