Pigeon's breastfeeding nipple, designed for babies to drink naturally. I bought these as spares, but didn't end up using them, so I'm selling them. I will slightly indent the tip of the nipple and flatten the box for shipping. Please understand this before purchasing. m(_ _)m - Brand: Pigeon - Size: LL - Age: 9 months and up - Quantity: 2 pieces Thank you for looking.
