This adaptor fits on top of the Nanobebe Breastmilk Bottle / Medela / Dr Browns / Pigeon narrow neck bottles and can then be used with the Jiffi Portable and Home Bottle Warmers. 

PLEASE NOTE:

Due to the narrow neck of the Nanobebe Breastmilk Bottle / Medela / Dr Browns / Pigeon narrow neck bottles, the Jiffi Portable Formula Dispenser is not compatible with these bottle brands as the dispenser opening is too wide.
