Features:
You can place the ice cubes in a drink, but you can't add to hot drinks. After taking the ice cube out of the liquid, please wipe off the liquid on the surface as soon as possible to minimise power consumption. It doesn't have to be in the liquid to light up, and it will light up when you press it with your hand. Batteries are not replaceable!
12-20 hours Battery life. 
Packing list:
12 x LED Ice Cubes
