All my balloons are BRAND NEW deluxe helium quality from the manufacturer, I buy in bulk and repackage in ziploc bags. They are not filled, you can fill at your local store, or rent a helium tank from your local party store or welding company. You can also air fill it and tape to the wall or attach balloon sticks. Please note that latex balloons last about 8-24 hours when filled, best to inflate just prior to your party.
