Our colourful printed Foild Balloons made of thin metallic foild are must have accessories for children's birthday parties and all other kinds of joyful events. The Foil Balloons can be filled with oxygen or helium. When filled with helium, the balloons float in the air and are guaranteed fun for young and old. Once the percentage of helium inside the balloon is too low compared to the percentage of oxygen, the Foil Balloon will still look very decorative but not float anymore and turn into a "normal" balloon. Order your Foil Balloon online and make a beautiful present.
