Product Contents: The balloons are 35 cm in height. Foil balloons are shipped deflated. Inflate the balloon through the valve at the bottom using the straw included in the package. After inflating the balloon, when you remove the straw, the valve automatically prevents air from escaping. There is no need to tie the valve part with string or anything else. After inflating all the balloons, you can stick them to a wall, window, or wherever you wish by attaching double-sided tape to the back of the balloon.
