The NUK Nature Sense Bottle is made of high-quality plastic (PP), is BPA-free and hard-wearing. The extra-wide bottle neck means it can be filled and cleaned in no time at all and the protective cap closes all the tiny openings to prevent leakage when mixing formula or when out and about.
For safety and hygiene purposes we recommend that you replace teats after 1-2 months of use or whenever they start to show signs of wear. Prior to sterilisation we recommend using the NUK Baby Bottle Cleanser, its natural formula removes dried on milk protein, pulp and juice residues more effectively than hot soapy water alone. To sterilise bottles and teats we recommend using steam, cold water sterilisation or a NUK Steam or Microwave Steriliser. We do not recommend dishwasher sterilisation as this can cause material damage.
