Glo Pals are light-up cubes that make it easier to encourage children to get in and out of the tub. Simply drop a pal in liquid and they will automatically glow, adding a unique dimension to your normal bath routine. Once you remove them from water, they automatically turn off. Each light-up cube offers an average of 36 hours of glow time, so it can last for several weeks. Package includes 4 Party Pal cubes; each cube lights up in various colors.
