if it doesnt open then its not a nursing bra.i got one off ebay too,which was described as nursing,but it was a maternity bra.(am wondering if you got it off the same person as me).i emailed her and she told me that mothercare described as nursing.i didnt take the matter any further (shouldve i know).ive had drop cup,zips (which i wore once ,trapped my skin and threw it away!!),and also had hook and eye type fastening,which was too tricky,so threw that one aswell!!def go into dispute.
