The natural origin is independently certified. The soft teat is made of pure natural rubber. A purely plant-based, renewable raw material, which is very soft and warm and is also particularly flexible. But NUK for Nature also means that sustainability does not stop with the soother. And to make the carbon footprint even smaller, everything from its raw materials to its production using renewable energy is optimised to be climate friendly. The original NUK shape is also inspired by nature: round at the top and flat underneath. So the NUK for Nature soother nestles against the palate and leaves room for the tongue.
