Get ready to step into the Red Zone with Red Light Up Ice Cubes! Ravishingly radiant Red Lighted Ice Cubes are great for Valentine's day events, Red theme parties and glow parties of all shapes and sizes! Glowing Red ice cubes can also be used to light up centerpieces, vases, ice displays and much, much more! Red glowing ice cubes come fully assembled with the batteries installed and have three different light settings - single flash, double flash and steady light (non-flashing). The duration of the Red LED ice cubes is 24 hours with the flashing setting and 12 hours on the steady light setting, so your light up ice cubes will last all night long! CrystalCube ice cubes are completely sealed, so they're 100% waterproof. Just turn them on and your glow party is ready to go!
