MSB Expiration Date



Why I can't find out period of validity (expiration date) for Breastmilk Storage Bags of Lansinoh that I bought? Does that mean they are counterfeit? How long do you recommend storing the bags? Unopened 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,
