No, you can only pump directly into the 100% leak-proof 360 milk bags that are designed specifically for the Willow 360 pump. The 360 milk bags are self-sealing and ready to store when removed from the pump. If you are pumping into containers, you can then transfer your breast milk into our Breast Milk Storage Bags with Willow 360.

The Willow app uses your phone’s camera to scan the information you’ve written on the bag. The app automatically inputs the date, volume, and bag ID into your digital stash so you always know how much milk you have stored and where.
