Perfect for a summer themed tropical party, especially outdoors with hanging lanterns amongst the trees. Why not team our happy birthday pineapples balloon with our plain gold foil balloons. Make them into bunches and tie onto a balloon weight. The balloon arrives un-inflated and has a self sealing valve. You can fill it with air or helium, it will need helium if you want it to float though. The float time of this balloon is around 7 days.
