PREMIUM HIGH-QUALITY LATEX: We monitor our balloons in the production process so they have a much higher latex content than the industry standard, which means they are made with thick heavy duty material that won't pop unless you want them to!
Generally, 12-inch latex balloons filled with helium will float between 6-10 hours.Balloons filled with air will stay inflated between 8-10 hours outdoors and 12-20 hours indoors.
