Thank you for viewing. Pigeon Mother's Milk Real Feeling Nipple S 2-piece set One has some discoloration due to use. The other has been used very little, so it has no discoloration and I think it's clean. I will bend the nipples when shipping. I am troubled by people who disappear after commenting.
