Period of validity (expiry date) for Breastmilk Storage Bags



Why I cann't find out Period of validity (expiry date) for Breastmilk Storage Bags of Lansinoh that I bought? Is it means that they are faker/ not real ones? How long do you recommand to keep your Breastmilk Storage Bags in a correct condition, not open in a dry atmosphere?

Thank you for your answer.

Best regards





the breastmilk storage bags do not expire so they do not have a expiration date.  They should last indefinitely if you keep them in a dry atmosphere and unopened.

Best wishes,
