Willow – 3.0 Spill-Proof Breast Milk Bag 48ct

Willow® 3.0 Spill-Proof Milk Bags make on-the-go pumping hassle-free. Patented, no-spill technology lets you pump directly into self-sealing storage bags. Each bag has a one-way valve so milk goes in and doesn’t come out. Each bag holds up to 4 oz. of milk. Attach the bag inside the pump – then toss it in your fridge or freezer when you’re finished. These bags are single use, not made with BPA, and recyclable. Lie down, bend over, play with baby, pump wherever life takes you!
