The highest quality latex Led balloons, these colour change balloons are fully compliant with European Testing requirements. Unlike a lot of LED balloons, the lights inside the balloon don\'t cause a harmful projectile risk when popped, and they can be used with both helium and air and lasting up to 24 hours. As easy to operate as a regular balloon, each balloon appears white and contains a colour change LED to give a funky, colourful effect that\'s perfect for parties and celebrations. Why not attach them to a balloon stick and cup to give the illusion of a helium balloon!
