Made from premium-grade foil, these "Happy Birthday" balloons are easy to inflate and simple to hang.
Each letter measures 16" (41cm) and can be inflated by inserting the supplied straw into the plastic valve at the bottom of each balloon and blowing into the straw.
Hanging the balloons couldn't be easier; simply thread the string through the small eyelet on every balloon, and attach the string to the wall at either end.
The balloons are made from premium grade foil, which is thick and uniformly coloured.
