My grand daughter has a thing about balloons and she loved these age 4 ones which I bought for her. They have been blown up for over a week now and have not even started to look as though they will deflate any time soon. Very pleased with quality.
Really pleased with these balloons as they are larger than supermarket ones, look cheerful and stay inflated for a VERY LONG TIME! (Birthday balloons are always left in our house to deflate or burst at their leisure... these ones went on for WEEKS :-)
