These are Pigeon brand nipples for baby bottles, size S and L, from the Mother's Milk Realization series. - Brand: Pigeon - Size: S - Size: L There are two in the package, but I only used one, so I'm offering the unused one. Please note that the nipples will be flattened for shipping to reduce the thickness. The box will not be included. Thank you. I am also selling other baby items.
