Blue LED Light up ice cubes with Push Button on/off. Push Button cubes last longer and work in ice, unlike cubes with moisture sensors (which only work when submerged in liquid). When on, the bright color operates in 3 modes: slow flash, fast flash, and steady on. When off, cubes are clear. FDA approved clear acrylic shell is sealed with freezable gel inside and is submersible safe in beverages. They are fun LED party lights that when mixed in with ice in the Party Barge, the light cubes provide a very nice light effect and help provide visibility. They can also be used in drinks. And if you're having trouble getting your little ones to take a bath, throw a few in the tub for fun illumination. They are attention getters in glasses and, when frozen, keep a glass of white or rose' wine chilled without diluting from ice.
Battery life is 24-36 hours. They will last longer in the blinking mode vs. the steady on mode so the variation of lifespan is determined by how they are used. Since most typical events range from 3 to 5 hours, the benefit is that they can be used multiple times for multiple events before the battery expires. Batteries cannot be replaced. Our cubes are sealed so that they are safe for use in drinks or in ice.
Packed: 12 each blue light ice cubes
