These are ultra-thin, uniquely shaped silicone nipple shields for breastfeeding. Purchased in May 2025. I used them with my first child, so I bought a new set for my second, but I didn't need them. One is unused, and the other has been used 2-3 times and sterilized. They were essential for my first child, and I found them helpful because they didn't hurt even when my baby started teething and biting! The box has some creases, but I'll include it if you want it (it may be folded). *If there are no purchases within a certain period, I plan to sell them to someone else.* - Brand: medela - Product Name: Contact Nipple Shields - Size: S - Quantity: 2 pieces - Material: Silicone - Features: Ultra-thin, unique shape
