Perfect for filling with air or helium for ceiling balloons (air filled balloons will not float). These professional quality latex balloons can be air or helium filled and can be inflated to 40 cm (16 inches). When inflated with helium these balloons will last approximately 8-14 hours depending on the climate/conditions. Made from natural rubber (latex), these balloons are bio-degradable. These balloons can have their life extended with Hi-Float treatment, which allows for an extra 24 hours float time, at a cost of an extra $1.50 per balloon. Sold individually inflated plain balloons are $3.95 each. Inflated balloons are available for delivery in the Sydney metro area only. Please call our store to order. Please note that there is a minimum purchase quantity for balloon deliveries plus a delivery charge depending on where/when delivery is required. Alternatively inflated balloons can be ordered and collected from our store.
