This Baby Boy Shape Foil Balloon can be inflated with normal air through a straw/pump which you insert into the valve (will not float away).
Size: 21" x 30"
It can also be inflated with helium (will float away) so they should be tightened to a weight. They last for a few hours.
Tip: Do not overinflate the balloon, it can pop!
