A party essential, these helium quality Powder Blue Pearlized Latex Balloons inflate to 11 inches high and gleam with a pearly light blue finish. Fill them with helium for up to 18 hours of flying time indoors; extend time aloft by pre-coating with balloon treatment (sold separately). 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 72 pearlized 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.
