Breastfeeding Realization Nipple (without bottle) - Brand: Pigeon - Quantity: SS 2 pieces, S 4 pieces Total: 6 pieces Thank you for viewing. I used the SS size for 1 month and the S size for 2 months, alternating between them. I have one S box left, so I will include it folded. Please note that I will not send items not shown in the images. I used a microwave for sterilization. Since these were used by an infant, please refrain from purchasing if you are concerned about minor scratches, etc. I will compress them as shown in the image for shipping.
