How green is your party? These glowing helium quality Kiwi Green Latex Balloons inflate to 12 inches high for a lively accent of floating greenery. Fill them with helium for up to 10 hours of flying time indoors. Fill them with air, and the heavy latex material ensures they’ll remain inflated for days on end. Seal the balloons by knotting the neck, tying them off with ribbon or string, or using one of our plastic balloon clips. Package contains 100 Kiwi Green Latex Balloons. Note: Balloon arrives uninflated. To inflate it with helium please visit your closest Wanna Party store or contact any helium gas provider near you. Filling charges are extra.
