Pigeon Mother's Milk Realization Nipple M size, 2 pieces. Used for about 3 months. I am selling them because I no longer use them. These are used and second-hand items, so please refrain from purchasing if you are sensitive to such things. They are genuine products, so the [Pigeon] logo is on the back. * There are teeth marks. Please check the condition of the nipples (see photos) before purchasing. * To offer them at a low price and reduce shipping costs, we will fold the nipples for shipping. Please refrain from purchasing if you are sensitive to this. Thank you for looking.
