Our non-toxic natural rubber nipples are an easy sustainable option, rather than replacing the entire bottle. The 2-pack teats are cherry shaped and have an anti-colic valve, thoughtfully produced with one mould to make them highly hygienic. Soft and durable in your babies mouth and soothing for the teething stage. These teats will fit our glass bottles and all regular neck bottles. You can sterilize in boiling water, but because of the natural rubber please do not clean in the dishwasher or steamer.
