How to inflate the foil balloons correctly
These foil balloons are not elastic, so inflate slowly. Do not use an automatic air pump. For best results, fill to 80–90% capacity, not 100%. This prevents overstretching and helps them stay afloat longer if filled with helium. You can use air or helium—both work fine.
Where can you hang the 12th birthday decorations?
Hang the banner and balloons anywhere indoors or outdoors: ceiling, garden, doorway, or room walls. The set is suitable for both boys and girls and works well for anniversary celebrations or any special event you want to decorate.
Can you reuse the balloons for other parties?
Yes, all foil balloons can be deflated and reused many times for future parties or events. Store them carefully after use.
