• BPA Free. • All NUK soothers are approved by the British oral health foundation for promoting healthy oral development. • Orthodontic shape which mimics a mother\'s nipple during breastfeeding for a more natural soothing experience. • Especially kind to teeth - reduces pressure on baby\'s jaw and teeth. 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. A 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. The NUK air system helps to ensure the mouthpiece remains soft and flexible, encouraging the correct development of your child\'s teeth. Integrated grooves enable saliva to flow away from the baby’s mouth preventing skin irritations. The soother box can be cleaned hygienically in the microwave oven within 4 minutes, following these instructions: first, fill each side of the box with 20ml water and put in the pacifier. Close the box and heat on 700-1000w for 4 minutes. The steam in this process prepares the pacifier hygienically. Leave the microwave closed for another 5 minutes. Empty out any water remaining. Leave soothers to dry in the open box. Additional details: Packaging size: 60mm x 140mm x 60mm Recommended age: 6-18m
