Each Milk Stork cooler comes with Lansinoh storage bags. The 34 oz. coolers include 6 bags and the 72 oz. coolers include 12 bags. International coolers include 24 storage bags.
If you choose to use your own, please make sure to pack enough of your preferred bags to support your trip and take care not to exceed the capacity of your cooler. Please be advised using Willow or Kiinde bags will slightly reduce the amount of milk that you will be able to pack in the cooler.
