Rainbow Birthday Candle

Is there any moment quite as special as blowing out candles on a birthday cake? Add some extra fun to your child’s colourful birthday celebration with this delightful large rainbow birthday candle. It is available to order individually or as part of our full Rainbow themed party box, alongside all our other rainbow birthday party supplies.

Helium Free Indoor Options

If you’re planning to host your party indoors, we have an economic, helium-free option for setting up your balloons. 3M ceiling hooks and Clik Hangs are included in our Rainbow party box, allowing you to hang the balloons directly from your ceiling. This means you’ll save the cost and trouble of filling them up with helium. If you want to set up your party outdoors, you will need to purchase helium and extra balloon weights from a local party supplier.

Balloon Garland Assembly

The balloon garland will take you around 2 hours to assemble, depending on your experience. Click here for our video tutorial on putting it together. If you’re in Auckland, we also provide a balloon assembly service. Fees are $120 (including GST) per garland pick up from Flat Bush, or $165 (including GST) for delivery within Auckland Central. For inquiries about the availability of our assembly service, please contact us at 021-1819990.
