“Hurray finally schoolchild” stands on this 45 cm balloon in rainbow colors and is therefore perfect for every schoolchild!

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 refilling. When cold, the balloon contracts, with heat, the balloon expands, which is why storage at about 20 C is recommended.
