With a gentle polka-dot pattern, this Happy Birthday foil balloon is perfect for every birthday! The balloon has a diameter of 45cm.

This foil balloon is printed on both sides in a unique and state-of-the-art process – directly in Germany – with the highest quality. It can be filled with air and helium and has a self-closing valve , so that several refills are possible. Due to the high-quality material, the suspension time with helium is at least 7 days, which can be extended by re-filling. When cold, the balloon contracts, with heat, the balloon expands, which is why storage at about 20C is recommended.
