The vast majority of our balloons do not ship inflated and will need to be inflated locally once they are delivered. This is done for several reasons such as them taking up more space when they are inflated, the possibility of them bursting during shipment, the possibility of them deflating during shipment, etc. Most customers either purchase a disposable helium tank, which can usually be found at local stores or take their balloons to a nearby party store to have them inflated. We do ship some air-fill (i.e. not helium filled) 4 inch, 9 inch and other smaller decorative balloons pre-inflated. These balloons will state that they are pre-inflated in the item name and/or description on our website.
