"SILVERETTE ® are small cups crafted out of 925 sterling silver that fit over and help to protect nipples while breastfeeding. Silver is a natural antimicrobial, antifungal, and antibacterial metal that also contains anti-inflammatory agents. ""These can be lifesavers from anyone with sore or damaged nipples. The antibacterial properties of silver, and the fact that you don’t need to apply a topical cream that can potentially cause adverse effects, makes these nursing cups a game changer for those early days of breastfeeding."" - Jacqueline Kincer, IBCLC, CSOM, Founder & CEO of Holistic Lactation"
