Breast milk pads - 31 pieces The large bag has been opened, but the contents are individually wrapped, so I believe there are no hygiene issues. Because they are individually wrapped, you can easily change them even if there is a difference between the left and right breasts, making them hygienic and easy to use. How about these for those who are preparing for childbirth and want to have breast milk pads just in case, or for those who want to try breast milk pads? Please purchase only if you understand that they are stored at home. Also, to ship compactly, I will take them out of the large bag and compress them for packaging. Please understand about wrinkles, etc.
