Purchased in June. Used once, for about 10 minutes, but didn’t end up needing. “Made of 999 pure silver, these Nursing Cups help soothe and protect sore, cracked nipples. Silver is naturally antimicrobial, antibacterial, antifungal and has anti-inflammatory benefits to support relief. A perforated design in the surface helps improve breathability, also reducing the weight of the shields which can be helpful if worn daily. No other creams or lotions are needed, and the cups won’t affect the taste of breastmilk for baby.”
