Learn how to set up your Rainbow Number 7 giant foil balloon in a box for a 70th birthday. Step-by-step instructions for a hassle-free display.
Quick answer
Unbox the Rainbow Number 7 balloon, attach the ribbon, add the weight, and place the message card. It’s ready to display in minutes.
Why choose a balloon in a box?
A pre-inflated balloon in a box saves you the hassle of helium or air pumps. The Rainbow Number 7 arrives fully inflated and ready to use, so you can focus on other party prep.
What’s inside the box?
The package includes the inflated giant foil balloon (86cm / 34 in), a ribbon, a balloon weight, and a personalised message card. Note that the box color and design may vary from the image.
Step-by-step setup
- Open the box carefully: Remove the lid and lift out the inflated balloon. The balloon is already inflated, so avoid sharp objects or rough handling. Keep the box away from pets or small children to prevent accidental popping.
- Attach the ribbon: Tie the provided ribbon securely to the balloon’s knot. Make a double knot to ensure it stays put. A loose ribbon can cause the balloon to drift or fall, so check the knot is tight.
- Add the balloon weight: Attach the weight to the end of the ribbon. This keeps the balloon from floating away and helps it stand upright. Place the weight on a flat surface so the balloon doesn’t tip over.
- Insert the message card: Write your personalised message on the card and place it next to the balloon or tie it to the ribbon. Use the card as a focal point—guests will read it first.
- Display and enjoy: Position the balloon in a visible spot, such as near the cake table or entrance. The balloon stays inflated for up to one week. Avoid direct sunlight or heat sources to prolong the balloon’s life.
