Pump n Save BPA-free Medela milk storage bags are especially designed to allow directing pumping (from Medela's breast pumps). The milk bags feature zipper and flat bottom, allowing the bags to stand on their own.

Note that this model is based a special tie-up feature that uses a yellow ribbon to keep the bag attached to the breastshield. This should not be confused with another model that requires special adapter.

Each box comes with 20 milk bags.
