Get the party started in a big way. Our Royal Purple Premium Latex Balloons feature a cool purple shade, glossy finish and make a big statement with their size. These large, helium-quality latex balloons are a great addition to any party's decorations. Each balloon inflates to 36in. HI-FLOAT balloon treatment is a solution of a plastic material dissolved in water. It forms a coating inside latex balloons that greatly reduces helium or air loss. With HI-FLOAT, party decorations can be prepared a day ahead of time, and balloon bouquets will float for several days. You can choose the Light Up Balloon Stick to turn your existing balloon into floating night lights! WARNING: CHOKING HAZARD - Children under 8 years can choke or suffocate on uninflated or broken balloons. Adult supervision required. Keep uninflated balloons from children. Discard broken balloons at once.
