The NUK Space pacifier is designed with extra-large openings that optimize air circulation and allow the skin to breathe, which is perfect for the baby's sensitive skin. Its improved original shape is based on the mother's nipple during breastfeeding, providing a natural and satisfying sensation. In addition, this pacifier promotes healthy development of the teeth and jaw by exercising the baby's lips, tongue, and facial muscles. Made in Germany and BPA-free, this pacifier is widely accepted by babies and recommended by mothers. It also includes a reusable carrying case that can be placed in the microwave.
