All my balloons are BRAND NEW deluxe helium quality from the manufacturer. 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 mylar balloons last about 1-2 weeks when inflated although actual float time varies. Latex balloons will only last -24 hours so be sure to inflate just prior to your party. Balloons are Brand New and purchased by me in bulk and sent to you unwrapped and folded.
