How long will a balloon stay up for?

Most foil balloons will float for a week to 10 days+. A Latex balloon’s float time depends on the size and type of balloon.  Our 11” latex balloons are of really good quality and will float for around 18 + hours untreated.  We treat our latex balloons (with Fairy Dust) and have gotten as much as 3 weeks out of them although they can shrink a little everyday.
