Set of 2 "Mama Substitute Milk" bottles. I bought these thinking they would be necessary for raising twins, but we didn't use them much, so I'm selling them. There isn't much noticeable staining, but there are a few faint spots. There's also some slight fuzzing. They have been washed at home. As I am a private seller, there may be some overlooked stains, etc. Please understand and consider before purchasing. The photos were taken at night, so they may be difficult to see. If you would like to see other photos, please comment. I may change the shipping method from Rakuraku Mercari Bin to Yu-Yu Mercari Bin. Please understand.
