Pigeon Breastfeeding Realization nipples, size SS, set of 4. Used for approximately 2 months. All items were purchased this year. They were disinfected each time after use, hand-washed with detergent, and then steam sterilized. Please note that although I will sterilize everything before packing, please be sure to wash and disinfect them before using them for your precious child after purchase. There are no noticeable scratches or discoloration on the outside, but there may be oversights. I would like to sell these to someone who understands that they are used items. They will be shipped slightly flattened. If you have any questions, please feel free to comment! - Brand: Pigeon, Breastfeeding Realization - Size: SS - Quantity: 4
