These breast pads for nursing moms are hand cut and crafted with comfortable microfleece on one side and leak proof PUL on the other side. Sandwiched in-between these layers is an absorbent microfiber core. The soft fleece wicks the moisture away from the skin into the absorbent center. The leak-proof PUL keeps the moisture on the inside of the pad and off of your shirt. Sold three pairs of breast pads per package. Colors may vary. Each pad is approximately 4.5" in diameter.
