Setup, Compatibility & Care
To inflate the balloon, gently insert a helium nozzle or a thin straw into the designated opening at the base. Inflate slowly to avoid over-stretching the foil seams. Once the balloon reaches its full 45cm diameter, remove the nozzle; the internal valve will seal automatically.
For care, keep the balloon away from sharp objects and extreme heat, as both can damage the foil material or cause the gas inside to expand too quickly. To deflate for storage, carefully re-insert a thin straw into the valve to gently release the air, flatten the balloon, and store it in a cool, dry place.
