Bag of 50 white BIODEGRADABLE cups & sticks. One Piece means that the cup and the stick are in one piece. For use of air filled balloons only. These are made of plastic and are approximately 16" long. Once inflated with air, the balloon neck can then be twisted around the little cup end on the stick and will then take the appearance of being sturdy and upright. A great way to hand out the balloons to people. Air filled balloons stay inflated for up to a week.
