11" printed latex balloons are available flat in bags of 10,25,50 pieces.

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 12 hrs so always inflate these balloons just before they are needed. Click4 recommends treating latex balloons with Hi-Float balloon treatment which will extend the float-time when using helium from 12 hrs up to 3 days.
