This 21st birthday foil balloon is ideal as a gift or to decorate your celebration venue. Requires helium filling.
Foil balloons require no tying as they automatically seal once filled with helium. They last on average 3-5 days and can be refilled. In a cold draught they may slightly deflate but once warm and draft free they usually plump up again. Don't forget to buy ribbon and weights to secure the balloon.
The balloon measures 21" at the maximum point.
