  • Great balloon
Color: Gold Size: 4
Big gold foil ballon! Holds helium for many days! Great color and super easy to fill with helium or air! Nice price for the quality of the balloon! Floats perfectly with other balloons! Nice and thick material very durable!

  • Great quality!
Color: Blue Size: 7
I purchased this balloon to decorate for a birthday. It came folded up in a plastic bag with a straw and some balloon string. The balloon itself was intact, without any holes. It was simple to blow up. You simply gently insert the straw into the hole at the tip of the balloon and blow air through until it is fully inflated. It holds air for quite a while; we had it up for probably over a month. The color is bright and beautiful. Definitely worth the money and I would purchase again. ... show more

  • Ripped Balloon in Multiple Places
Color: Rainbow Size: 5
Unfortunately my balloon came with not one, but three rips in the seam of the balloon. It was not taken out of the package until this morning for the party. There was no damage to the package so I have to assume it's due to poor product quality.

  • Perfect size
Color: Rainbow Size: 5
Good quality and perfect size. I accidentally got a hole on it, I had to use tape to cover the hole. Other than that, it was good. Perfect size for balloon stands!
