Shade may vary. The NUK Genius Soother has been developed in partnership with dental experts worldwide, and is the new generation of NUK Soother. Still based on the approved orthodontic NUK shape, but improved with a softer and more flexible baglet, to further reduce the pressure on baby's jaw and teeth, as well as the risk of teeth misalignment. The NUK Air System helps to ensure the mouthpiece remains soft and flexible, encouraging the correct development of your child's teeth whilst integrated grooves enable saliva to flow away from the baby¿s mouth preventing skin irritations.  The handy reusable storage case can be used to keep the soothers safe and clean but also to hygienically clean the soothers with steam in the microwave. BPA Free.
