Rocket Balloon Refills - QTY 30

My kids launched these non-stop at the birthday party, and the thin rubber really does stretch easily without popping. Each pack gave us plenty of flight time before they needed a new one.

These refill balloons stretched and inflated without a single weak spot, and the whole pack lasted through two full birthday party rounds. My kids launched them over and over until the rubber finally gave out, which took some serious abuse.

The 30-pack is a decent value, though a few balloons had weak seams and wouldn't hold air for long. When they do stay sealed, they shoot across the room just as fast as the original pack.
