Happy Birthday foil balloon, 340x35cm, silver Metallic Happy Birthday phrase

When transporting balloons:

• Keep the car’s air conditioner on (20-23°C) before loading.

• Upon arrival, bring them indoors immediately to a room at 20-23°C.

• Never leave balloons in a hot car or trunk.

 
To extend float time:

• Avoid extreme temperatures—heat can cause bursting, while cold may make them deflate.

• Handle with care and avoid squeezing them into small spaces.
