This fun Birthday Block Party Foil Balloon by Unique Party is perfect to decorate a boys Birthday Party. Decorate the party location for a Block, Lego or Duplo Party with this round Happy Birthday Block Party foil ballon. The colourful happy birthday balloon printed on both sides should not be missing on the birthday and sets great accents as a floating party decoration.

The foil ballon is sold deflated and requires air or helium inflation. Simply slide the nozzle of the pump in the opening and inflate. The Happy Birthday foil balloon is self sealing, so just remove the nozzle from the balloon and press the valve flat to seal. Do not tie the ribbon arount the valve of the balloon or a leak may occur. To fill the balloon with normal air, it is best to use a straw that leads into the balloon and pull it out again after inflation so that the balloon is closed.

The foil balloon can be filled with helium for a surcharge in the warehouse in Wettswil if you pick it up yourself. The balloon will fly for about 14 days and can be refilled with helium or air at any time. Not suitable for children under 3 years of age as small parts can cause a choking hazard. Use only under adult supervision.
