Great for Working Moms
I purchased these to store my breast milk discretely at work in the refrigerator. They're perfect for keeping breast milk cool. I pack one cup of milk between each of the packs and then put the milk in an air-tight lunch box in my fridge at work. The bags stay frozen until the lunch bag remains in the fridge and the milk stays perfectly chilled until I get back home to store it in the freezer.
