Pump Faster, Live Fuller. Not enough milk? Painful pump? Always leaking? We know what bothers moms about pumping from detailed community interviews, so we are here with our pump star Momcozy S12 Pro hands-free breast pump, which is so convenient that it can make you forget you are still pumping! As soft as a baby’s lips and as collecting as a baby’s mouth, our S12 Pro wearable breast pump has an upgraded double-sealed flange design compared to the normal single-flange ones, which can snug tighter and closer to your breasts to not only pump more efficiently and more comfortably but also prevent milk from leaking effectively!
