Set of 50 80ml breast milk freezer bags and 1 size M nipple. A few freezer bags have been used from the right side, but the left side is unopened. Please note that there is only one bottle nipple! It has been stored in a place where dust does not collect, but Please refrain from purchasing if you are concerned about cleanliness. If you don't need the box when shipping, I will discount it by 200 yen, so please let me know in the comments. I hope this will be helpful to someone.
