A must for all parents whose infants have sore gums! Twistshake's teething cooler is water-filled, keeping it chilled so that your baby's gums feel nice and cool as the first teeth emerge. The material has a textured surface, giving a nice massage, and the hook-shaped design makes the teething ring easy to hold from all angles. It is also easy to hold by its ring-shaped handgrip - perfect for an infant's hands. Store in a refrigerator before use. Choose from a variety of beautiful colours!
