This is a set of two LL-sized nipples for baby bottles, designed to feel like breastfeeding. - Brand: Pigeon - Model: Breastfeeding Realization LL Size - Quantity: Set of 2 - Target Age: 9 months and up - Size: LL - Shape: Y-cut I bought these when I thought I would need them, but ended up not using them, so I'm selling them. They are unopened. It is also possible to purchase only one. *The price can be lowered if you only need the contents shipped.* Thank you for looking.
