Hooray for Qualatex for inventing this new latex CHROME balloon line. These new chrome balloons are amazing - their shiny metallic finish makes them look like a piece of art and they are so new and unique - there is nothing else like them in the balloon industry today. These balloons are 11 inches in size and come in packs of 8 balloons. Balloons arrive flat and need to filled with helium on the day of your event. You can take them to a grocery store or party store for helium or you can use a Balloon Time tank and fill them yourself. Ships in 1 to 2 business days by USPS First Class mail. Balloons with arrive deflated and require helium to float.
