11 Qualatex Latex Balloon. Qualatex balloons are manufactured to exacting quality standards and are considered The Very Best balloons you can buy.;We have a full color range of Qualatex balloons available in all colors / shapes and sizes! Be sure to search our Amazon store for all your requirements!;Qualatex Balloons are manufactured in the U.S.A. and will hold helium and will float longer than cheap foreign made balloons - the latex is thicker slowing oxidization and the release of helium - resulting in much longer float times.;Increase float time by up to ten times using an amazing product called Hi-Float - it coats the inside of the latex balloon slowing oxidization - average float time of an 11 balloon increases to 10-14 days. We've had them float for up to 45 days (temperature and humidity will affect float time - we make no claim to actual float time you will achieve)
