Silicone nipple for baby bottles, designed for natural feeding, size S, comes in a box of 2. Purchased in July and August 2025, used for 2 months. - Brand: Pigeon - Size: S - Quantity: Total of 4 - Material: Silicone rubber - Target age: 1 month and up Thank you for viewing. I was rotating between 6 nipples, so I think these can still be used for another 4 months. Please purchase only if you understand that these are used. * Discount available if purchased with other baby items.
