Pigeon Mother's Milk Real Feel Direct-Attach Baby Bottle 200ml Set Clear (Low Burden, High Flow) - Two Sets. - Brand: Pigeon - Quantity: 2 bottles - Included: 2 nipples, 2 caps Thank you for viewing. These were used for about a month, alternating between the two bottles. After each use, they were washed and sterilized immediately, so the bottles themselves have no noticeable stains. However, both nipples have become white due to the sterilizing solution. Therefore, if you do not need the nipples, please let me know in the comments after purchase, and I will dispose of them. As these are used items, I would appreciate it if those who understand the nature of used goods would consider purchasing. Because I have a small child, I have set the shipping time to 4-7 days just in case, but I will try to ship as quickly as possible.
