Have a celebration red and white balloons helium balloons suitable bestellt.Wollten this actually a day fill with helium before, but after we heard in a balloon business that such helium balloons suitable maximum 12hrs. hold your breath while the whole time losing air that came out of the question for the decoration. We then normally inflated with air, held great and so we were able to decorate one day in advance! So top. But you should advance by the seller out show that helium stops just a few hours, since the latex membrane is not impermeable to helium. Therefore a star deduction!
