11" Landmark Birthday '60' Latex Balloons.

Category: Happy Birthday Balloons
Size: 11" diameter using approx. 0.5 cubic feet of helium gas per balloon.
These latex balloons can be either air-filled or helium-inflated.
The average float-time of non-treated latex balloons inflated with helium gas is approximately 10-12 hrs so always inflate these balloons just before they are needed on the day of use. Click4 recommends either making or buying a Balloon Sizer to help you accurately inflated these balloons to the correct 11" diameter to ensure your balloons look uniform, decrease chance of burstage and avoid wasting helium gas.
