Medela Breastmilk Labeling & Storage System #67345

This is Medela's version of the Milkmate storage system. It only comes with 2 bottles, so you have to go buy the other 4 to fill up the rack, but if you want to use 8oz bottles instead (to store more milk in less space) then this is the storage rack you want. I recommend this more for fridge use than freezer. If you want the 5 oz bottles and want the system with the bottles to fill it up, then get the Milkmate Storage System instead.
