Pros: Inexpensive, good quality
I WOH full-time and have used a LOT of breastmilk storage bags, and these are my favorites. In terms of quality, I find them equal to the Lansinoh bags, but I prefer these because they're less expensive and have less waste. (The Lansinoh bags have 2 plastic "dispenser" bags inside the box of 50 bags and the plastic seal at the top to rip off and throw away, neither of which you'll find with this brand). They're available at Target and are now branded by Nuk, not Gerber. I pay about $7-8 for a box of 50, compared to ~10 for Lansinoh.
