These balloons are simply for decoration of a 18th birthday to. They looked really great and are totally durable. Have this early in the evening of 9:10. up puffs, purely celebrated from 10 to 11 October and these balloons released at 04.00 clock in the morning to "burst". My son also has some of them can save and those living today, 2:11:14, in his room. They have slightly lost air. Just TOP these balloons !! Can I fully recommend !!
