The Autumnz Silicone Breast Milk Collector Shell, also known as a Silicone Breast Pad, is a device designed to collect breast milk leakage during breastfeeding or pumping. It's made from soft, flexible silicone for comfortable wear inside a bra. Unlike breast pads that absorb milk, the collector shells passively gather milk that would otherwise be lost, allowing you to save it for later use. They typically feature a spout for easy pouring and are reusable after cleaning and sterilizing. It can also protect sore nipples and prevent chafing from clothing.
