I thought as it was a special birthday I would buy these balloons, the colours were nice but the quality is terrible. We started blowing them up, put them to one side and 2 burst, we started to put the others around the lounge and an hour later another one burst then, the morning of the birthday another one burst, again in the evening and during the night more burst. We have animals in the house and the noise of these balloons bursting scared them to death it was like gunfire, so loud. I thought that they would just go down like normal balloons, but we are now living on tender- hooks waiting until the next one bursts. So in view of this save your money.
They don't make balloons like they used to, maybe they are made elsewhere in the world now!
