Rifco and Cattex brand roud balloons – 6 foot in diameter. 2 neck sizes available. Some performers prefer the normal neck size as they get a better seal especially when the balloon is around their neck with their head popping out. If you use this size it is best to cut the lip off the balloon before inflating. Use very sharp scissors and do not leave any jagged edges as these can start a rip.
The wide neck can be used without removing the neck.
