This product is a balloon with a non-movable LED light affixed inside. The LED fixed inside lasts for long hours which is enough to add a glow to your kid's party. To activate the LED, hold the top of the ball from one side and pull the tab off the neck from the other side. Once inflated, tie a knot at the neck of the balloon to prevent it from flattening. The balloons are made of thick latex rubber material and last for a longer time. They can be used to decorate the area be it indoors or outdoors for a party or celebration.
