These balloons are supplied un-inflated
These large 11" 21st balloons will make ideal party decorations for anyone about to celebrate this landmark birthday.
The balloons are diamond clear and have a pattern of confetti and streamers with the number 21 printed all over in white.
These professional quality 21st birthday balloons are made from 100% latex and are biodegradable. They can be filled with air or helium for floating party decorations. They are suitable to use with our disposable helium canisters and self sealing balloon valves.
Inflate only to the designated size - do not over inflate. We recommend you use a balloon pump to inflate your air-filled balloons.
While air filled latex balloons will stay inflated for several weeks, balloons filled with helium usually float for 8 to 12 hours, so you will need to inflate them immediately before your party or event. Treated with Hi-Float, they will last for over a week and can be inflated in advance.
