Sposie storage bags, covered every month.
Every ounce you pump is worth protecting. Sposie breast milk storage bags seal it safely — a double-zipper leak-proof closure, a built-in temperature sensor strip, and freezer-safe, BPA-free material made for the milk your body worked for.
And here's the part most moms miss: storage bags are a covered benefit. Most insurance plans provide 100 Sposie bags every 30 days after baby is born — fully covered, shipped to your door, no out-of-pocket cost.
