Bunch O Balloons allows you to quickly fill and tie 100 water balloons in 60 seconds by attaching the stem to a standard hose. The patented O-ring technology eliminates the need for manual tying, as the balloons self-seal for fast preparation. This set includes 10 stems, producing over 330 self-sealing water balloons in Tropical Party colors for outdoor play. The stems and caps are made from certified recycled plastic, while the balloons are constructed from natural rubber derived from plants. The design prioritizes both speed and sustainability for summer water activities.
