Frequently asked questions

How are 30th birthday balloons delivered?
They are inflated with helium, fitted with ribbon and a weight, and packed in a box. When the box is opened, the balloons float out ready to display, with no helium tank needed.
What colours do the 30th balloons come in?
Choose from black and gold, black and silver, rose gold, green, rainbow and more, as single number balloons, bunches and larger balloon displays.
How long will a "30" number balloon float?
Foil number balloons usually float for 3 to 5 days indoors, sometimes up to a week, and bubble balloons for 1 to 2 weeks. Warm rooms, sunlight and draughts shorten float time. More on float times.
Which delivery date should I choose?
Choose the day before the party or celebration and a 1 Day (next day) delivery service at checkout. That gives a safety margin while the balloons still look their best on the day. Delivery information.
Can I add a message to the balloons?
Selected 30th designs can carry a name or a short message, and the option appears on the product page when it is available. They are made to order, so check the wording carefully before you buy.
