Water Pals are made from natural rubber, which means they sink when thrown into a swimming pool! The kids will have loads of fun diving to get these brightly colored friends. These bathtub pals will be an absolute hit at bath time, too. Large drainage holes allow for quick drying after playtime, which minimizes the possibility of mold growth. Cleans easily in the dishwasher (top rack). Made from sustainably harvested natural rubber. Age 2 years and up. Blue Diver.
