Total of 100 bags. The kiinde twist feeding system is a GAME CHANGER for new moms. You can pump directly into the pouch, store breast milk, feed directly from and then you toss/recycle it. This minimizes dishes 🙌🏼 and is safer for your baby because it eliminates milk transfers AND eliminates the potential to spill your breast milk since you aren’t pouring back and forth from a bottle. I have a ton, comment if you would like me to customize a listing ❤️❤️ Also compatible with the foodii system!
