It's not a party without balloons. Set the scene for a great time with our Royal Blue Latex Balloons. The solid blue balloons can be inflated with helium or air, and the heavy latex material will keep the balloons inflated for at least 18 hours. Mix the balloons with other solid or printed balloons to make brilliantly colorful balloon bouquets, for your party or special occasion. Each balloon inflates to 9in. Package contains 20 Royal Blue Latex Balloons. 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. NOTE: Balloons Arrive Uninflated.
