The concept of these balloons with the LEDs inside is great. There are 5 balloons in the pack and before the balloon is inflated a tab is pulled to activate the lights. I tried one and the light was bright and the balloon inflated well. I will be saving the rest for my next outside get together as these balloons will provide a nice light and be a focal point.
I received this product for free or at a discount in exchange for my honest and unbiased review.
