These quad balloons are great at creating quick and colorful centerpieces on a budget. To create a centerpiece: String together by running twine or string to a top piece ( we recommend a themed 18" Mylar balloon) and tie or tape to the bottom using either a balloon weight or a cardboard. Or stack directly on a column balloon stand. An easy way to create centerpiece for any event! * Easy to inflate * Self Sealing * 0.75" hole in the middle * 50 pieces pack
