Big changes start with small steps. Thats why we created the NUK for Nature collection, to little by little make a big impact. With 70 years of experience, we are proud to do our part to design a better future for our little ones and their planet. Our NUK for Nature Comfy Pacifier is made with 100% bio-based sustainable silicone* so parents can feel good about doing their part. We use renewable resources like sugar beets and other plant components to create our sustainable pacifiers, which are REDcert-certified, so your little one can enjoy something that’s both comforting and wholesome. NUK for Nature Comfy Pacifiers are made with 100% silicone for soft comfort and feature a heart-shaped design for a perfect fit. This baby pacifier is BPA-free and dishwasher-safe (top rack only).
