Light up your celebration with our LED Blinky Balloons! Our 14 inch white LED balloons have three lighting modes, which can be changed by pressing the button at the base of the balloon: slow blink, fast blink, and steady on. Our Blinky Balloons are the ONLY reusable light up balloons on the market that can be inflated by mouth! No helium tank required. When helium is used, these high quality balloons will stay afloat for up to 10 hours. The LED lights will last for up to 15 hours of continued use, and the batteries are replaceable. Each package includes 50 fully assembled balloons. Batteries are included and installed. Patent pending.
